     DETAILED DESCRIPTION 
     The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section. 
     One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details. 
     As advancements are made in electronic technology, the size of semiconductor chips, such as complementary metal-oxide-semiconductor (CMOS) chips, increasingly becomes smaller. To achieve desired electronic functionality in semiconductor chips, it can be desirable to be able to have or form a relatively large amount of electronic components, such as, for example, inductors, and electronic components of various sizes on a semiconductor chip. Employing techniques, such as direct print patterning to create electronic components, like inductors, on semiconductor chips can be inefficient, can result in undesirably larger component sizes, and/or can result in undesirable component performance. 
     The various embodiments described herein relate to generating enhanced inductors and other enhanced electronic devices. A device generator component can deposit a low-k dielectric film on a pre-built device level(s) and form a circular guide pattern in the film, wherein a circular notch or region, comprising the low-k dielectric film, can remain in the center of the circular guide pattern. The device generator component can perform a directed-self assembly (DSA) co-polymer deposition on the circular guide pattern, and DSA annealing on the co-polymer material to form two polymers in the form of alternating concentric rings that can surround the circular notch of low-k dielectric film. The device generator component can perform a loop cut in a portion of the concentric rings to form concentric segments (e.g., concentric semi-circular segments) and can fill the loop cut region with an insulator material (e.g., an oxide-based insulator material). 
     The device generator component can selectively remove the first polymer from the concentric segments that contain the first polymer to form a space between the respective concentric segments formed of the second polymer, fill such space with a low-k dielectric, and planarize a top surface (e.g., perform chemical-mechanical planarization (CMP) on the surface) of the concentric segments formed of the second polymer material, the concentric segments formed of the low-k dielectric material, the insulator material in the loop cut region, and/or the low-k dielectric film of the circular notch. The device generator component can selectively remove the second polymer to form a space between the respective concentric segments formed of the low-k dielectric material, fill such space with a conductive material (e.g., a copper-based material), and planarize a top surface of the concentric segments formed of the low-k dielectric material, the concentric segments formed of the conductive material, the insulator material in the loop cut region, and/or the low-k dielectric film of the circular notch. The device generator component can deposit a low-k film on top of the respective concentric segments (e.g., segments formed of conductive material, and segments formed of low-k dielectric material) and insulator material that filled in the loop cut portion. 
     The device generator component can form vias in the low-k film, wherein each via can span from an end of one concentric segment (e.g., concentric segment of conductive material) across the insulator material of the loop cut region to an end of another concentric segment (e.g., another concentric segment of conductive material). The device generator component can fill the vias with conductive material to form conductive connectors (e.g., conductive vias) to form a substantially spiral conductive structure. When the electronic device, comprising the substantially spiral conductive structure, is an inductor device, the inductor device can enhance (e.g., increase) the number of turns or rings of the inductor per a given area, can correspondingly reduce the pitch of the inductor, and can enhance (e.g., increase) the inductance level produced by an inductor spanning the given area. 
     These and other aspects and embodiments of the disclosed subject matter will now be described with respect to the drawings. 
       FIG. 1  illustrates a block diagram an example, non-limiting system  100  that can be employed to generate inductors or other types of electronic devices, in accordance with various aspects and embodiments of the disclosed subject matter. The system  100  can comprise a device generator component  102  that can be utilized to generate an electronic device  104  that can comprise an enhanced spiral structure (e.g., enhanced spiral conductive structure) for use in providing a desired electronic functionality (e.g., producing desirable inductance, or providing another desired electronic functionality). In some embodiments, the electronic device  104  can be or can comprise an inductor. For example, the electronic device  104  can be a device that can comprise various types of electronic and/or mechanical components and/or functions, wherein the electronic device  104  can comprise one or more inductors. As another example, the electronic device  104  can be an inductor or can be a device that can primarily comprise an inductor. In other embodiments, the electronic device  104  can be another type of electronic device, with or without an inductor, that can employ the enhanced spiral structure for a desired utility or application. 
     It is to be appreciated and understood that, while a number of aspects, embodiments, and features of the disclosed subject matter are described herein with regard to an inductor, the disclosed subject matter is not so limited, and various aspects, embodiments, and features of the disclosed subject matter can be applicable to other types of electronic devices, besides inductors, and the disclosed subject matter can be utilized to generate such other types of electronic devices. 
     The device generator component  102  can employ DSA processes (e.g., co-polymer deposition, DSA annealing, . . . ) and other processes to facilitate creating the enhanced spiral structure of the electronic device  104 , as more fully described herein. Referring to  FIG. 2  (along with  FIG. 1 ),  FIG. 2  depicts a diagram of a top view and side view (A-A′ view) of an example electronic device  104  comprising an enhanced spiral structure, in accordance with various aspects and embodiments of the disclosed subject matter. The electronic device  104  can comprise a layered structure (e.g., layered stack structure) that can be formed on a substrate  106  by the device generator component  102 . The material used for the substrate  106  can vary. In an aspect, the substrate  106  can comprise a silicon wafer. In some embodiments, the substrate  106  can comprise silicon dioxide on top of a silicon wafer. In other embodiments, the substrate can comprise a compound semiconductor, such as, for example, Indium gallium arsenide (InGaAs) or indium phosphide (InP). 
     The device generator component  102  can generate, form, or build one or more pre-built device levels  108  (e.g., one or more layers comprising respective electronic components) on the electronic device  104 , wherein the one or more pre-built device levels  108  can be formed on the substrate  106 . The one or more pre-built device levels  108  can comprise transistors, wiring, and/or other electronic components that can be formed on the respective levels (e.g., layers) of the one or more pre-built device levels  108 . The transistors, wiring, and/or other electronic components of the one or more pre-built device levels  108  can be structured and arranged to form desired electronic circuitry that can perform desired electronic functions of the electronic device  104 . 
     The device generator component  102  can generate, form, or build an enhanced spiral structure  110  (e.g., an enhanced spiral or substantially spiral structure) that can be part of the electronic device  104 , wherein the enhanced spiral structure  110  can be formed on a pre-built device level  108  (e.g., the top pre-built device level), and wherein the enhanced spiral structure  110  can be formed in a circular guide pattern that can be formed in a low-k dielectric film layer  112  that was deposited on the pre-built device level  108 , as more fully described herein. In some embodiments, the forming of the circular guide pattern in the low-k dielectric film layer  112  can include selective application of low-k dielectric material to the top surface of the top pre-built device level  108 , or selective removal of low-k dielectric material from the low-k dielectric film layer  112  deposited on the top pre-built device level  108 , to have the circular guide pattern remain and defined by (e.g., surrounded or bounded by) the low-k dielectric material (e.g., the applied or remaining low-k dielectric material) of the low-k dielectric film layer  112 , wherein the circular guide pattern can include a center region  114  (e.g., a circular region) that can be in the center, or at least can be substantially in the center, of the circular guide pattern. 
     The low-k dielectric material can comprise virtually any type of dielectric material that has a sufficiently low dielectric constant value (e.g., dielectric constant k&lt;3.9) relative to silicon oxide. The low-k dielectric material can be, for example, a dielectric material comprising atoms of at least silicon (Si), carbon (C), oxygen (O), and hydrogen (H) (e.g., a SiCOH-type dielectric material); methylsilane (CH3-SiH3); tetramethylsilane (Si(CH3)4); and/or another desired (e.g., suitable, acceptable, or optimal) low-k dielectric material. The low-k dielectric film layer  112  can have a desired thickness, which can range from 50 nanometers (nm) to 500 nm, for example. The low-k dielectric film layer  112  can be formed using a desired process, wherein the desired process can comprise, but is not limited to, a physical vapor deposition process, a chemical vapor deposition process, a spin-on deposition process, or a combination thereof. 
     The enhanced spiral structure  110  can be sized and shaped (e.g., circular or substantially circular) to cover (e.g., to span) a desired amount of area of the electronic device  104 . For example, the enhanced spiral structure  110  can have a diameter that can be on the order of tens of microns (e.g., the diameter can typically range up to 100 microns, or can even be larger than 100 microns). The enhanced spiral structure  110  can have a desired and defined height. 
     The device generator component  102  can create or form the enhanced spiral structure  110  to have the enhanced spiral structure  110  comprise respective concentric segments (e.g., semi-circular segments), which can include a first type of concentric segments  116  that can be formed of an insulator material (e.g., a desired low-k dielectric material) and a second type of concentric segments  118  that can be formed of a desired conductive material (e.g., copper (Cu), a copper-based material, or other conductive material). Respective concentric segments  118  of the second type can be interspersed or interposed between respective concentric segments  116  of the first type, for example, as illustrated in  FIG. 2 . The respective concentric segments  118  and respective concentric segments  116  can each have respective ends (e.g., segment ends) to form open regions of the respective concentric segments  118  and respective concentric segments  116 . As more fully described herein, the open regions can be formed or defined by, and located in, a loop cut region by the device generator component  102 , wherein the device generator component  102  can fill the loop cut region with a desired insulator material  120 , such as, for example, silicon oxide, silicon oxynitride, carbon-doped silicon oxide, another desired oxide-based material, or another type of insulator material. The device generator component  102  can planarize at least the surface of the insulator material  120  of the loop cut region, using a desired planarization process (e.g., CMP). 
     It is to be appreciated and understood that, the first type of concentric segments  116  comprising an insulator material and the second type of concentric segments  118  comprising the desired conductive material can be formed or derived as a result of various processes, including DSA processes and material removal or stripping (e.g., selective removal or stripping) processes, and/or other processes, as more fully described herein. 
     In some embodiments, the device generator component  102  can form or deposit a dielectric film layer  122  on top of the respective concentric segments  116 , respective concentric segments  118 , the insulator material  120  of the loop cut region, and center region  114 . The dielectric film layer  122  can have a desired thickness, which can range from 50 nm to 500 nm, for example. In certain embodiments, the dielectric film layer  122  can be formed using a desired low-k dielectric material or another type of insulating material (e.g., an electrically insulating material). 
     The device generator component  102  can form, cut, or etch vias in the dielectric film layer  122 , wherein each via can span from an end of one concentric segment  118  (e.g., concentric segment formed of conductive material) across the insulator material  120  of the loop cut region to an end of another (e.g., an adjacent or a proximately located) concentric segment  118  (e.g., concentric segment formed of conductive material and adjacent or proximately located to the one concentric segment  118  associated with the same via). The device generator component  102  can fill the vias with conductive material to form conductive connectors  124  (e.g., conductive vias) to facilitate forming the enhanced spiral structure  110  (e.g., a spiral or substantially spiral conductive structure). To form the conductive connectors  124 , the vias can be filled with a desired conductive material (e.g., a metal) including, but not limited to, copper, indium-tin oxide, indium-zinc oxide, aluminum-zinc oxide, titanium, aluminum molybdenum, cobalt, silver, gold, nickel, tungsten, chromium, hafnium, platinum, iron, and/or their alloys. 
     The device generator component  102  can planarize respective surfaces (e.g., respective top or open facing surfaces) of the conductive connectors  124  and/or the dielectric film layer  122  of the electronic device  104 . In some embodiments, the device generator component  102  can perform CMP on the respective surfaces of the conductive connectors  124  and/or dielectric film layer  122 , although in other embodiments, the device generator component  102  can employ another type (e.g., a suitable type) of planarization process to planarize or polish the respective surfaces of the dielectric film layer  122  and conductive connectors  124  of the electronic device  104 . 
     The enhanced spiral structure  110  of the electronic device  104  can comprise a spiraling conductive formation that can comprise a desired (e.g., enhanced or improved) number of turns or loops over a given area, a desirably reduced (e.g., an improved reduction in) pitch between respective concentric segments  118  of the enhanced spiral structure  110 , and, with respect to an inductor, can enhance (e.g., increase) the inductance level produced by an inductor spanning the given area. For example, for a given chip area of approximately 2.5 μm×2.5 μm, an electronic device  104  structured as an inductor, with a circular or substantially circular shape, can have a pitch of 60 nm and an inductance of 0.34 nanohenries (nH), whereas, for that same given chip area, another type of inductor, having a square inductor shape and formed using direct print patterning, can have a pitch of 100 nm and an inductance of 0.16 nH. 
     It is to be appreciated and understood that, while the concentric rings are often described herein as being circular in shape, and the concentric segments derived from the concentric rings are often described herein as being semi-circular in shape, the disclosed subject matter is not so limited. In some embodiments, the device generator component  102  can create the rings or segments to have a different shape, such as rectangular or square rings and/or semi-rectangular or semi-square segments. It is to be further appreciated and understood that the enhanced spiral structure  110 , with the semi-circular segments, disclosed herein, can be structured more efficiently and can operate more efficiently (e.g., can have a smaller pitch, can provide a higher inductance, for a given chip area), as compared to inductors having different shapes (e.g., rectangular, square), even when DSA processes are employed for such different shapes, and even more so when other types of processes (e.g., direct print patterning) are employed. 
     These and other embodiments and aspects relating to the formation of the electronic device will be further described with regard to the other drawings. 
     Referring briefly to  FIG. 3  (along with  FIG. 1 ),  FIG. 3  illustrates a diagram of a top view and side view (A-A′ view) of an example portion  300  of the electronic device  104  during fabrication (e.g., creation, formation) of the electronic device  104 , in accordance with various aspects and embodiments of the disclosed subject matter. Repetitive description of like elements employed in other embodiments described herein is or may be omitted for sake of brevity. 
     In accordance with the electronic-device fabrication process and the example portion  300  of the electronic device  104 , the device generator component  102  can generate, form, or build one or more pre-built device levels  108  on the substrate  106  of the electronic device  104 , as more fully described herein. The device generator component  102  can form or deposit the low-k dielectric film layer  112  on a top level (e.g., a top surface of a top level) of the one or more pre-built device levels  108 . In some embodiments, the device generator component  102  can selectively apply (e.g., form, deposit) the low-k dielectric film layer  112  to portions of the top pre-built device level  108  to form a desired circular guide pattern  302  having a desired size, with the circular guide pattern  302  comprising the center region  114 . In other embodiments, the device generator component  102  can apply the low-k dielectric material on the top surface of the top pre-built device level  108  and can selectively remove desired portions of the low-k dielectric material to create the circular guide pattern  302  and center region  114  using a desired material removal process. While the low-k dielectric film layer  112  is described herein as being comprised of low-k dielectric material, it is to be appreciated and understood that other types of materials (e.g., other types of insulating materials) can be used in other embodiments, in accordance with the disclosed subject matter. This can facilitate preparing for the DSA process and other processes that can be performed to facilitate creating the electronic device  104 , as disclosed herein. 
     Turning to  FIG. 4  (along with  FIG. 1 ),  FIG. 4  presents a diagram of a top view and side view (A-A′ view) of an example portion  400  of the electronic device  104  during fabrication (e.g., creation, formation) of the electronic device  104 , wherein the electronic-device fabrication process can comprise using DSA co-polymer deposition to facilitate generating (e.g., creating, forming) the electronic device  104 , in accordance with various aspects and embodiments of the disclosed subject matter. Repetitive description of like elements employed in other embodiments described herein is or may be omitted for sake of brevity. 
     In accordance with the electronic-device fabrication process and the example portion  400  of the electronic device  104 , the device generator component  102  can utilize a DSA process (e.g., DSA block copolymer deposition process) to deposit a co-polymer material  402  (e.g., polystyrene-polymethylmethacrylate (PS-PMMA), polystyrene-polydimethylsiloxane (PS-PDMS), polystyrene-poly(2-vinylpyridine) (PS-P2VP) or other desirable (e.g., suitable, acceptable, or optimal) co-polymer material) into the circular guide pattern  302  that can be defined in part by the low-k dielectric material (e.g., applied or remaining low-k dielectric material) of the low-k dielectric film layer  112  and center region  114  formed on the top surface of the top pre-built device level  108 . The co-polymer material  402  can comprise a combination of multiple polymer materials (e.g., two (or more) co-polymer materials), wherein the co-polymer material  402  can facilitate the generation of respective concentric rings of respective co-polymer materials, as more fully described herein. The thickness of the co-polymer material  402  can be the same as, or substantially the same as, the thickness of the low-k dielectric film layer  112 . 
     Referring to  FIG. 5  (along with  FIG. 1  and  FIG. 4 ),  FIG. 5  illustrates a diagram of a top view and side view (A-A′ view) of an example portion  500  of the electronic device  104  during fabrication of the electronic device  104 , wherein the electronic-device fabrication process can comprise using DSA annealing to form respective concentric rings of respective polymer materials to facilitate generating (e.g., creating, forming) the electronic device  104 , in accordance with various aspects and embodiments of the disclosed subject matter. Repetitive description of like elements employed in other embodiments described herein is or may be omitted for sake of brevity. 
     In accordance with the electronic-device fabrication process and the example portion  500  of the electronic device  104 , the device generator component  102  can perform DSA annealing on the co-polymer material  402  (of  FIG. 4 ) to create (e.g., generate, form) respective concentric rings of respective polymer materials formed or located in the circular guide pattern  302 , which can be defined in part by the low-k dielectric material (e.g., the applied or remaining low-k dielectric material) of the low-k dielectric film layer  112  and center region  114  formed on the top surface of the top pre-built device level  108 , wherein the respective polymer materials can be derived from the co-polymer material  402 . Through the DSA processes performed by the device generator component  102 , the co-polymer material  402  can be transformed and the respective polymer materials of the co-polymer material  402  can undergo a directed-self assembly to form the respective concentric rings of the respective polymer materials. 
     The respective concentric rings can comprise a first subset (e.g., type) of concentric rings comprising concentric rings  502  of a first polymer material and a second subset (e.g., type) of concentric rings comprising concentric rings  504  of a second polymer material, wherein the first polymer material can be different from the second polymer material. The respective concentric rings (e.g.,  502 ,  504 ) can progressively extend or expand out from the center region  114  through the circular guide pattern  302  to the outer end of the circular guide pattern  302  that can be framed or defined by the outer portion of the low-k dielectric film layer  112  (e.g., the outer portion of the applied or remaining low-k dielectric material of the low-k dielectric film layer  112 ), wherein the concentric rings can be arranged in an alternating manner such that the concentric rings  504  can be interspersed or interposed between respective concentric rings  502 . 
     In some embodiments, the first subset concentric rings  502  can be formed of a poly(methyl methacrylate) (PMMA) material, and the second subset of concentric rings  504  can be formed of a polystyrene (PS) material. In other embodiments, the first subset concentric rings  502  can be formed of another type of polymer material, and/or the second subset of concentric rings  504  can be formed of still another type of polymer material that can be different from the polymer material of the first subset of concentric rings. 
     It is to be appreciated and understood that, while the disclosed subject matter describes using DSA processes to create the respective concentric rings of respective polymer materials (e.g., concentric rings alternating between a first-type ring (e.g.,  502 ) of one polymer material and a second-type ring (e.g.,  504 ) having a different polymer material), the disclosed subject matter is not so limited, and the disclosed subject matter (e.g., the device generator component  102 ) can employ any suitable process(es) to form the respective concentric rings of respective polymer materials described herein.

     At  1532 , the vias can be filled with a conductive material to form conductive connectors that connect, for each pair of adjacent second (e.g., conductive) concentric segments, an end of one second concentric segment to an end of the other second concentric segment to form an enhanced spiral structure of the electronic device. The device generator component can deposit the conductive material in the vias to form the conductive connectors and, as a result, can connect, for each pair of adjacent or proximately located conductive concentric segments, the end of one conductive concentric segment to the end of the other conductive concentric segment, using a conductive connector, to form the enhanced spiral structure of the electronic device. The conductive connectors can span across or over the desired insulator material of the loop cut region to connect the respective ends of the respective conductive concentric segments to each other. 
     At  1534 , the surfaces of at least the conductive connectors can be planarized. The device generator component can planarize or polish the surfaces (e.g., top surfaces) of at least the conductive connectors. In some embodiments, the device generator component also can planarize or polish the first concentric segments comprising the low-k dielectric material, the second concentric segments comprising the conductive material, the insulator material in the loop cut region, and/or the low-k dielectric film that bounds the circular guide pattern. In certain embodiments, the planarization can be CMP.

     One or more embodiments may be a system, a method, an apparatus and/or a computer program product at any possible technical detail level of integration. The computer program product can include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the one or more embodiments. The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium can be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium can also include the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network can comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. Computer readable program instructions for carrying out operations of the disclosed subject matter can be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions can execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer can be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection can be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) can execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the disclosed subject matter. 
     Aspects of disclosed subject matter are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the subject disclosure. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. These computer readable program instructions can be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create method for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions can also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. The computer readable program instructions can also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational acts to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the disclosed subject matter. In this regard, each block in the flowchart or block diagrams can represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks can occur out of the order noted in the Figures. For example, two blocks shown in succession can, in fact, be executed substantially concurrently, or the blocks can sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
     While the subject matter has been described above in the general context of computer-executable instructions of a computer program product that runs on a computer and/or computers, those skilled in the art will recognize that this disclosure also can be implemented in combination with other program modules. Generally, program modules include routines, programs, components, data structures, etc. that perform particular tasks and/or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the computer-implemented methods disclosed herein can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as computers, hand-held computing devices (e.g., PDA, phone), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. However, some, if not all aspects of this disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices. 
     As used in this application, the terms “component,” “system,” “platform,” “interface,” and the like, can refer to and/or can include a computer-related entity or an entity related to an operational machine with one or more specific functionalities. The entities disclosed herein can be either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component.

In another example, respective components can execute from various computer readable media having various data structures stored thereon. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor. In such a case, the processor can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, wherein the electronic components can include a processor or other method to execute software or firmware that confers at least in part the functionality of the electronic components. In an aspect, a component can emulate an electronic component via a virtual machine, e.g., within a cloud computing system. 
     In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. As used herein, the terms “example” and/or “exemplary” are utilized to mean serving as an example, instance, or illustration. For the avoidance of doubt, the subject matter disclosed herein is not limited by such examples. In addition, any aspect or design described herein as an “example” and/or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs, nor is it meant to preclude equivalent exemplary structures and techniques known to those of ordinary skill in the art. 
     As it is employed in the subject specification, the term “processor” can refer to substantially any computing processing unit or device comprising, but not limited to, single-core processors; single-processors with software multithread execution capability; multi-core processors; multi-core processors with software multithread execution capability; multi-core processors with hardware multithread technology; parallel platforms; and parallel platforms with distributed shared memory.

Further, processors can exploit nano-scale architectures such as, but not limited to, molecular and quantum-dot based transistors, switches and gates, in order to optimize space usage or enhance performance of user equipment. A processor can also be implemented as a combination of computing processing units. In this disclosure, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component are utilized to refer to “memory components,” entities embodied in a “memory,” or components comprising a memory. It is to be appreciated that memory and/or memory components described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), flash memory, or nonvolatile random access memory (RAM) (e.g., ferroelectric RAM (FeRAM)). Volatile memory can include RAM, which can act as external cache memory, for example. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), direct Rambus RAM (DRRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM (RDRAM). Additionally, the disclosed memory components of systems or computer-implemented methods herein are intended to include, without being limited to including, these and any other suitable types of memory. 
     What has been described above include mere examples of systems and computer-implemented methods. It is, of course, not possible to describe every conceivable combination of components or computer-implemented methods for purposes of describing this disclosure, but one of ordinary skill in the art can recognize that many further combinations and permutations of this disclosure are possible. Furthermore, to the extent that the terms “includes,” “has,” “possesses,” and the like are used in the detailed description, claims, appendices and drawings such terms are intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim. The descriptions of the various embodiments have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
