Compact Thermal Modelling of Sub-20-nm Nanowire MOSFETs for Circuit Applications

Short channel effects (SCE) and self-heating be- comes more critical as the technology reaches on the nanoscale. Nanowire MOSFETs are an assuring candidate for coming CMOS technology. Due to the self-heating carrier mobility is decreased, which results in drain current degradation. Self- heating consequences in sub-20-nm Nanowire MOSFETs are studied and a compact thermal model is proposed in this work applying well-calibrated three-dimensional TCAD electro- thermal simulations. In this work, we observed that a different characteristic result of channel length towards thermal resistance. When the channel length is reduced, thermal resistance appears to be down gradually. The model is successfully implemented in BSIMCMG compact model. Compact thermal model for Nanowire MOSFET is proposed based on empirically extracted equations on different device parameters like channel length, nanowire thickness, nanowire height and fin pitch. The model may remain helpful for the evaluation of thermal resistance in Nanowire MOSFETs with large layouts.
Wear and Oxidation Behaviour of Tungsten Carbide Based Coatings: A Review

Failure of components under severe environment caused by the diversity of wear mechanisms and oxidation necessitated to understand, which is fundamental to estimate durability and reliability of coatings. Abrasive and erosion wear contributed to the maximum failure rate encountered in real life situations. In high-temperature applications, oxidation leads to deterioration in desired properties which causes premature failure of machine or system components. Tungsten carbide (WC) based coatings serve with both types of wears and furthermore deals with high-temperature serviceability. Among the pure metals tungsten exhibits uppermost relative abrasive and erosion resistance which provides the base for utilization of WC based coatings for severe wear applications. The emphasis of this review is on wear and oxidation performance of tungsten carbide based coatings developed by different thermal spray techniques.

Multimodal Biometrics for Personal Identification using Human Foot Prints: A Review

Biometrics is a technology used to identify and analyze an individual’s physical and behavioral characteristics. Unimodal biometrics uses only one characteristic to identify a person. But it often fails to accomplish the desired performance requirements due to certain limitations. To overcome the problems of unimodal biometrics, Multimodal biometric system got its importance which encompasses more than one traits of a person for the identification, verification and authorization. This paper mainly focuses on the foot modality and would explore the related work done in the field of multimodal biometrics for personal identification. The paper presents various techniques developed so far for recognizing a person’s identity using foot geometry and footprint structure.
Improved Mirai Bot Scanner Summation Algorithm

Mirai is the most dangerous Distributed Denial of Service (DDoS)-capable IoT malware to date that is in the wild and yet very simple in nature. Mirai attack an array of Internet of Things (IoT) and embedded devices that ranges from Digital Video Recorders (DVRs), Internet Protocol (IP) cameras, routers and printers recruiting them to form a botnet. The biggest DDoS attack in history was executed using Mirai botnet. A recent study proposed the Mirai Bot Scanner Summation Prototype that analyzes the network traffic generated from Mirai bot host discovery. The Mirai Bot Scanner Summation Algorithm however, cannot recognize if a network traffic is truly Mirai bot host discovery traffic or not. Given any network traffic, the Mirai Bot Scanner Summation Prototype will proceed to summate and output number of bots, retransmission packets, number of packets and number of potential victim IoT devices using only the source Internet Protocol (IP) address and destination IP address of a packet without identifying if it is truly a Mirai bot host discovery packet or not. This paper present an Improved Mirai Bot Scanner Summation Algorithm that looks at the packet to determine whether it is a truly packet generated due to Mirai bot host discovery by looking at the TCP flag of the packet and the port number of the packet. To perform a host discovery Mirai bot sends out SYN packet over TELNET port 23 or 2323 to a randomly generated non-governmental IP addresses to establish a TCP 3-way handshake with a potentially vulnerable IoT device. The Improved Mirai Bot Scanner Summation Algorithm uses this condition to determine whether a packet is a Mirai bot host discovery packet or not. The Mirai Bot Scanner Summation Algorithm and the Improved Mirai Bot Scanner Summation Algorithm are evaluated using IoT Network Intrusion Dataset. The evaluation results have shown that the Improved Mirai Bot Scanner Summation Algorithm provides more accurate results than the Mirai Bot Scanner Summation Algorithm.

H xMoO 3-Y Nanobelts: An Excellent Alternative to Carbon Electrode for High Performance Mesoscopic Perovskite Solar Cells

The forming Schottky barrier between carbon and perovskite has currently been the bottlenecks to improve the performance of carbon-based hole-conductor-free perovskite solar cells (C-PSCs). A conventional approach to resolving this issue is incorporating a hole-transport material (HTM) in the mesoscopic skeleton or chemical modification of the carbon electrode. Here, we show an innovative strategy that using solution-processed hydrogen molybdenum bronzes (HxMoO3-y) nanobelts, an n-type HTM with high work function and electrical conductivity, as the sole electrode material to enhance the hole-extraction process and result in efficient PSCs for the first time. The mesoscopic cell configuration of FTO/c-TiO2/m-TiO2/m-Al2O3/HxMoO3-y with perovskite infiltration delivered a champion power conversion efficiency (PCE) of 14.5%, which compares favorably with that of 13.3% for the typical high temperature C-PSCs. The increase in cell efficiency stems primarily from the enhancement in open circuit voltage and short circuit current, which is owed to the HxMoO3-y electrode with more favorable energy alignment and higher hole-extraction ability than carbon electrode. These results open up the potential of HxMoO3-y nanobelts as an efficient electrode for realizing high-performance and low-cost mesoscopic PSCs.
Applications of Biomaterials for Immunosuppression in Tissue Repair and Regeneration

The immune system is essential for tissue repair and regeneration. Regardless of innate or adaptive immune responses, immunosuppressive strategies such as macrophage polarization and regulatory T (Treg) cells induction can be utilized to modulate the immune system to stimulate tissue repair and regeneration. Biomaterials provide an ideal platform which can serve as scaffolds to support damaged tissues and function as carriers to deliver immunosuppressive factors such as cytokines, drugs, microRNA, growth factors and stem cells. Herein, we present an overview of the immunosuppressive modulation by biomaterials in tissue regeneration and highlight the mechanisms of macrophage polarization and Treg cells induction. Overall, we propose that future biomaterials for regenerative strategies will not only involve more interactions between biomaterials and the immune system, but also require more knowledge about mechanisms of immune suppression, which will further enhance the clinical application of biomaterials.
Numerical Investigation of Single Phase Gas Flow Through Straight, Wavy and Branched Wavy Minichannels

In this paper, a parametric numerical study was undertaken to understand and analyze the refinement in the heat transfer performances of straight minichannels due to employing wavy design. Three dimensional conjugated heat transfer simulation was analyzed using finite-volume based CFD approach in ANSYS 16.0 to evaluate laminar convective heat transfer characteristics on a minichannel heat sink purely on the basis of geometrical modifications. The results showed that there was a significant improvement in the heat dissipation capacity of heat sinks in wavy minichannels than observed in straight minichannels. Another novel concept of secondary branches is introduced to intensify macroscopic mixing by disrupting and reinitializing boundary layer development periodically across the newly formed branches. This further enhanced the thermal performance of heat sinks.
Computational Intelligence Techniques for Biometric Recognition: A Review

World is changing and growing very fast, especially in terms of technological advancement. Efficient, secure, &amp; reliable authentication systems are needed to society by these technological advancements. Biometrics provides a means for these needs. Biometric authentication systems are comparatively more fast and efficient. In fact they are more secure &amp; difficult to forge. But as there is nothing called complete in this world exists; similarly biometric systems also suffer many problems. This paper examines some of biometric systems with their merits and demerits. So many physiological and behavioral traits have element of uniqueness and by using them so many biometric systems been developed for environment specific needs and financial investments. There exists a number of commercial applications whose needs are so specific that a uniform and integrated biometric system is not feasible. For eg. Requirements of an attendance monitoring system at a project site are very different than KYC requirements for a financial body.
Study of Emotive EPOC in Limited Time Training for Cognitive Control in Casual Users

Brain computer interface (BCI) was created for establishing a communication channel for body locked or disabled individuals. However in recent years the shift in BCI market has healthy (casual) users in its target and a separate segment of BCI has come into existence known as Casual BCI. These BCIs have the training mode in which casual users can learn to control BCI actions and applications by imagining motor movements. They generally prefer Emotive EPOC headsets as it is cheap, wireless and light weight along with affective control. Till now none of the studies have explored the time effort index of this device. Hence in this work two simultaneous studies investigate the Time-Effort index along with the success rate of cognitive control. In first setup 6 participants moved a virtual cube in clockwise and anti-clockwise directions and in second setup they had the choice of pulling or pushing the cube. The first setup used a fixed scheme of training for 8 minutes whereas in the later setup the self directed training for 8 minutes was allowed. The detailed analysis with maximum cognitive control has been achieved illustrating the time-effort index in both the setups, which could be used for improving the usability of casual BCIs.
Thermal Barrier Coatings (Tbc) for High Temperature (Ht) Applications

Thermal barrier coating for higher temperature applications enables the structural components to operate above 1200°C. Most of the applications like gas turbines, chemical and oil refinery encounter such high-temperature related failure. The coating of thermally insulating coating over such components provides better protection and enable the enhancement on the life span and increase the repair and maintenance time span. The coating materials require higher melting temperature, high-temperature phase stability and low thermal conductivity. The coating materials based on rare earth pyrochlore structure shows an alternative for yttria-stabilised zirconia coatings. The coating methods atmospheric plasma spraying, HVOF spraying provides good defect-free and low-cost coating compared to complex electron beam assisted physical vapour deposition method. The coating testing like CMAS, Thermal shock and cyclic thermal test provides the life prediction of the coating material at operating conditions.

Biocomposites are the torch-bearers for the ‘environmentally sustainable manufacturing’ in current times. Also, their growing demand to meet the industrial application is also gathering momentum. Different manufacturing parameters are responsible for making biocomposites capable of matching the standards set by the convention petroleum origin products. In this paper, fiber lengths of three natural fibers used in the biocomposites are studied and their effects on the mechanical properties of the biocomposites are recorded. This paper helps to formulate a review of different natural fibers used and the influence fiber lengths on natural fibres exert on the mechanical properties of biocomposites such as tensile modulus, flexural modulus, flexural strength, fracture resistance and impact strength.
Consistency and Workability Properties of Bakery Ash in Self-Compacting Concrete for Sustainable Concrete Infrastructure

Workability, flow and consistency are unique parameters that contribute to the quality and mechanical properties of Self-Compacting Concrete (SCC) in the hardened stage, in a bid not to compromise strength and quality. Workability, flow and consistency can be controlled in the fresh stage of SCC. This research assessed the workability and strength properties of self-compacting concrete using bakery ash as the need for a green approach in concrete technology is paramount in track with the trash to treasure initiative. To achieve the aim of this study, two brands of Portland limestone cement were used in developing twelve (12) concrete samples. The additive was used at 0, 5,10,15,20 and 25% replacement of cement. The flow, segregation and filling ability were investigated using the L-box, V-Funnel and the slump flow apparatus. The result of the experimental research showed that at 10% and above addition of bakery ash, the workability was unsatisfactory using EFNARC specifications. The compressive strength increased up to 10% addition of the bakery ash. However, at higher percentage addition, the strength reduced. The use of this concrete is recommended for the construction of low load bearing concrete infrastructures. The outcome of this research will serve as a guide for engineers, researchers and construction worker on the optimum quantity of this waste in the development of self-compacting concrete with satisfactory rheology
Horizontal Mergers, Investments and Industry Evolution

Do horizontal mergers shape the way an industry evolves? I answer this question by investigating the non-merging rivals’ investments. Based on the stylized fact that the rivals’ performance on average declines in the three years following horizontal mergers, I find the rivals become more cost efficient. Specifically, their R&D, PP&E, and labor investments increase in the segments close to the merger’s industry. These segments appear to have higher Tobin’s Q. Firms with greater R&D increases experience more reductions in the cost of goods sold, SG&A, and higher asset turnovers. The investment allocations are more pronounced among the innovative rivals, the neck-and-neck rivals, and the unconstrained rivals. Overall, this paper helps us better understand how firms deal with competitive pressure through internal capital markets.

Ubiquitous Computing uses mobile phones or tiny devices for application development with sensors embedded in mobile phones. The information generated by these devices is a big task in collection and storage. For further, the data transmission to the intended destination is delay tolerant. In this paper, we made an attempt to propose a new security algorithm for providing security to Pervasive Computing Environment (PCE) system using Public-key Encryption (PKE) algorithm, Bio-metric Security (BS) algorithm and Visual Cryptography Scheme (VCS) algorithm. In the proposed PCE monitoring system it automates various home appliances using VCS and also provides security against intrusion using Zigbee IEEE 802.15. 4 based Sensor Network, GSM and Wi-Fi networks are embedded through a standard Home gateway.
Linking the Performance of Vanilla Options to the Volatility Premium

The advent of quantitative investing has made it increasingly important to understand the performance drivers of systematic strategies that use derivatives, such as those based on the sale of options. In this paper we introduce a new formulaic representation to analyse the performance of delta-hedged vanilla options and use this formula to break down the historical performance of foreign exchange straddles held to maturity. We show how, as is widely assumed, the performance is dictated in part by the so-called volatility premium, but also that another important driver is at play, the covariance between the convexity of the option and the prevailing volatility regime. In particular, we determine empirically that the sign of that driver’s contribution is tenor specific. These results can be used to size directional or relative value option strategies and to disentangle the impact of the various performance drivers in the booming field of systematic options strategies.
Strong Dual-Components Bioadhesive Based on Solventless Thiol-Isocyanate Click Chemistry

Isocyanate is an efficient tissue anchor for engineering of strong bioadhesive. However, isocyanate containing adhesives are seldom manufactured, due to their requirement of water-free administration and time-consuming moisture-induced solidification. To address this issue, herein, a solventless dual-component bioadhesive based on thiol-isocyanate crosslinking chemistry is reported. This dual-component bioadhesive consists of a hyperbranched polymer with thiol groups (HBPTE) and an isocyanate modified polyethylene glycol (PEGNCO). HBPTE and PEGNCO are low-viscosity fluids at room temperature and hence could be used directly as adhesive components, in absence of catalyst and solvent. The thiol-isocyanate click chemistry of components provide HBPTE-PEGNCO mixture with a gelation time of 1.5~3 minutes, which makes it acceptable for practical applications. The abundance of isocyanate groups in the adhesive molecule provides strong bonding strength through formation of chemical linkages with reactive groups on the tissue. Moreover, <i>in vitro</i> and <i>in vivo</i> evaluations in mice showed excellent biocompatibility of HBPTE-PEGNCO adhesive. This dual-component bioadhesive based on solventless thiol-isocyanate click chemistry displayed a fast gelation time and excellent bonding performance, providing a pioneering ideal for engineering isocyanate containing bioadhesive.
Measuring Work-Life Balance: Relationships with Work-Family Conflict and Family-Work Conflict

Work-life balance is a challenging and tremendous task, between managing work and family conﬂicts. Conﬂict arises based on the expected behaviour of the employees. The aim of the present research is measuring work-life balance with work-family conﬂict and family-work conﬂict. In addition, the paper aims to fnd out the different conﬂicts between work and family, and how to balance the work-life of the respondents. Instruments are adopted from previous research. The sample size is 157 and the data is collected from the respondents working in rural and urban areas of selected districts in Tamil Nadu. Data were analysed using the SPSS, for measuring reliability, validity, loadings, coeffcient, and model ft of the data. Employees need to spend more time with their family and friends to reduce stress and conﬂict. Employees realise that family members and co-workers are essential in maintaining work-life balance. Understanding and sharing work-related information with spouses leads to reduced work-family conﬂict. The research would help decision makers, employers, and employees enrich the employee’s work-life balance, through managing family and work conﬂicts.
