Integration of single-stage SPV generation to three-phase distribution grid using a variable step size LMS control technique

In this paper, an integration of single-stage solar photovoltaic (SPV) generation to three-phase distribution grid is proposed using a variable step-size least mean square (VSS-LMS) control technique. The prime focus of the system is to establish a safe, secure and reliable integration which mitigates several power quality issues like voltage fluctuations and flickers, harmonics distortion, DC current injections, reactive power requirement etc. and also provides load balancing, zero voltage regulation (ZVR) and power factor correction (PFC). A single-stage converter topology is used with VSS-LMS control and P&O (Perturb and Observe) based MPPT for achieving efficient system. For the verification of the system operation, a prototype is developed in the laboratory and tests are carried on it when subjected to different conditions like unbalanced nonlinear loads and variable solar insolation.
Beyond Machiavelli: Policy Analysis Comes of Age

Readers of Administrative Theory & Praxis are undoubtedly aware of criticisms of policy analysis and its reliance on economic theory and quantitative analysis. Indeed, members of the Public Administration Theory Network have written critiques of policy analysis as a field and as a profession. Scholars usingpostmodern frameworks, interpretive approaches, critical theory, and participatory research models (Denhardt, 1981; Fisher 1990; Majone 1989), have attacked the intellectual framework of policy analysis, the supposed neutrality of analysis, the use of "value-free" techniques, and the reliance on expertise at the possible expense of democratic values. It is important to note, however, that most of these critiques have been leveled by scholars outside of the field of policy analysis, and they have typically focused on policy analysis as it was practiced in the 1960s and 1970s during the heyday of Planning Programming and Budget Systems (PPBS), cost! benefit analysis, and linear programming. In contrast, Beryl Radin provides a critical assessment of policy analysis from the view of an insider within the policy analysis field in her book, Beyond Machiavelli: Policy Analysis Comes of Age. Beryl Radin, a former president of the Association for Public Policy Analysis and Management and a scholar with a long list of achievements in the field of policy analysis, provides both a history of the development of the policy analysis field and an assessment of what the discipline looks like today. In her assessment, policy analysis may have started as a technocratic profession focused on rationality, efficiency, and quantitative analysis, but she sees a much different role for policy analysts in the political system today. Profound changes in the policy environment have necessitated a dramatic transformation in the skills that are necessary for effective engagement in the policy process, and analysts in the real world of politics are just as likely to use bargaining, negotiation and facilitation skills as they are quantitative techniques. Because of these changes, she calls for a renewed commitment by policy scholars and public policy schools to assess the needs of modern policy analysts and refotm course offerings and graduate programs accordingly.
Identification of DNA motifs by two different models

The identification of DNA regulatory motifs (transcription factor binding sites) in co-regulated genes is essential for understanding the regulatory mechanisms. Many approaches have been developed for motifs discovery in the past. However, identification of regulatory motifs remains a significant challenge. In our opinion, the best motifs-finding methods may be those which rely on exhaustive enumeration because of their high reliability, whereas exhaustive enumeration becomes problematic for long and subtle motifs. In this paper, we present a new method to improve exhaustive enumeration using two different models. We tested its performance on both synthetic and realistic biological data. It proved to be successful in identifying very subtle motifs. Experiments also showed our method outperformed some popular methods in terms of our experimental data.
POSITION / FORCE CONTROL OF SYSTEMS SUBJECTED TO COMMUNICATON DELAYS AND INTERRUPTIONS IN BILATERAL TELEOPERATION

Teleoperation technology allows to remotely operate robotic (slave) systems located in hazardous, risky and distant environments. The human operator sends commands through the controller (master) system to execute the tasks from a distance. The operator is provided with necessary (visual, audio or haptic) feedback to accomplish the mission remotely. In bilateral teleoperation, continuous feedback from the remote environment is generated. Thus, the operator can handle the task as if the operator is in the remote environment relying on the relevant feedback. Since teleoperation deals with systems controlled from a distance, time delays and package losses in transmission of information are present. These communication failures affect the human perception and system stability, and thus, the ability of operator to handle the task successfully. The objective of this thesis is to investigate and develop a control algorithm, which utilizes model mediated teleoperation integrating parallel position/force controllers, to compensate for the instability issues and excessive forcing applied to the environment arising from communication failures. Model mediation technique is extended for three-degrees-of-freedom teleoperation and a parallel position/force controller, impedance controller, is integrated in the control algorithm. The proposed control method is experimentally tested by using Matlab Simulink blocksets for real-time experimentation in which haptic desktop devices, Novint Falcon and Phantom Desktop are configured as master and slave subsystems of the bilateral teleoperation. The results of these tests indicate that the stability and passivity of proposed bilateral teleoperation systems are preserved during constant and variable time delays and data losses while the position and force tracking test results provide acceptable performance with bounded errors. yapılmıştır.
Disk-Offload Middleware for Web-Services Using the Application-Caching Paradigm

Application-caching occurs when applications assume control for data caching rather then relying on middleware to manage their data. This paradigm is a good fit for"main-memory caching" in which data storage and retrieval issues are relatively straight-forward. However, the caching requirements of certain workloads exceed even modern main-memory capacity. Although disk-offload offers the potential to overcome this capacity constraint, it poses a problem for the application-caching paradigm since application data may now be resident in either main-memory or on disk. In this paper, we therefore examine how disk-offload middleware can best support the application-caching paradigm for data-centric web-services. We present two disk-offload caching architectures, evaluate their performance, and draw conclusions as to their relative effectiveness.
EGRET Observations of the Extragalactic Gamma-Ray Emission

The all-sky survey in high-energy gamma rays (E > 30 MeV) carried out by EGRET aboard the Compton Gamma Ray Observatory provides a unique opportunity to examine in detail the diffuse gamma-ray emission. The observed diffuse emission has a Galactic component arising from cosmic-ray interactions with the local interstellar gas and radiation, as well as an almost uniformly distributed component that is generally believed to originate outside the Galaxy. Through a careful study and removal of the Galactic diffuse emission, the flux, spectrum, and uniformity of the extragalactic emission are deduced. The analysis indicates that the extragalactic emission is well described by a power-law photon spectrum with an index of -(2.10 ± 0.03) in the 30 MeV to 100 GeV energy range. No large-scale spatial anisotropy or changes in the energy spectrum are observed in the deduced extragalactic emission. The most likely explanation for the origin of this extragalactic high-energy gamma-ray emission is that it arises primarily from unresolved gamma-ray-emitting blazars.
Through-Hole Contactless Slipring System Based on Rotating Magnetic Field for Rotary Applications

Contactless slipring system based on inductive power transfer is a preferable alternative to mechanical slipring assemblies. They are designed to deliver required output power to a rotary shaft without direct electrical contacts. The current single or multiple-unit through-hole single-phase systems often have limited power transfer capability within a confined physical space; thus, they may not be able to meet the load requirement for certain applications such as wind power pitch control. This paper presents an integrated polyphase through-hole contactless slipring system by generating a rotating primary magnetic field coupled with balanced power pickups at the secondary side with zero mechanical driving torque on the shaft. A new index termed “mutual inductance per pole” is introduced to simplify the analysis of the mutually coupled polyphase system to a single-phase basis. Simulation and practical experiments have demonstrated that, with the same physical size, the proposed contactless slipring setup can transfer 55% more power compared with the existing single-phase counterpart.
Resource allocation for MIMO multi-relay systems with zero-forcing relaying

In this paper, we consider a two-hop multiple-input multiple-output (MIMO) multiple relays communication networks, where each relay employs the zero-forcing (ZF) relaying scheme, we assume that the perfect channel state information (CSI) is available at the source, the destination and the relays. We propose a total relays power allocation (PA) scheme with the sum relays transmit power constraint to maximize the average system capacity. Since the original PA optimization problem is not convex, it is difficult to derive an analytical solution, so we propose to simplify the problem by employing the relaxed power constraint which is slightly higher than the actual sum relays power, then we derive the closed-form solution. The Monte Carlo simulation results shown that our proposed joint PA scheme significantly improves the system capacity compared with the conventional ZF relaying scheme.
Monitoring Patients with Mental Disorders

Mental disorders impose significant socio-economic and geo-political challenges which, if not addressed, have the potential to overwhelm the ability of healthcare systems globally to accommodate the growing demands both in human and resource management terms. From a treatment perspective there is a need to implement multi-modal systems where patients can be diagnosed, treated, and monitored. Such systems must incorporate triage and treatment capabilities in both hospital settings with monitoring in the community. This paper considers the practical challenges in realising the goal of achieving the effective monitoring of patients with mental disorders in Smart-Psychiatric Intensive Care Units and in the community. Illustrative scenarios are presented. We conclude that effective patient monitoring will provide benefits for all stakeholders in the management of mental disorders.
Blackhole and grayhole attacks in MANET

MANET is gaining more popularity due to two main characteristics, dynamic topology and no requirement of centralized administration. But due to these two properties, MANET is highly prone to various security attacks. One of the most important categories of attack is the Denial of Service (DoS) and the most important attacks under this category are the Blackhole and Grayhole Attacks. Lot of research work has been done to develop various techniques to mitigate the Blackhole and Grayhole attacks. This paper shows how the performance of the network is degraded due to these two attacks. This paper also provides the description of the various techniques that are used to detect and prevent these types of attacks.
Unraveling the Mystery of Cancer by Secretory microRNA: Horizontal microRNA Transfer between Living Cells

microRNAs (miRNAs) have been identified as a fine-tuner in a wide array of biological processes, including development, organogenesis, metabolism, and homeostasis. Deregulation of miRNAs causes diseases, especially cancer. This occurs through a variety of mechanisms, such as genetic alterations, epigenetic regulation, or altered expression of transcription factors, which target miRNAs. Recently, it was discovered that extracellular miRNAs circulate in the blood of both healthy and diseased patients. Since RNase is abundant in the bloodstream, most of the secretory miRNAs are contained in apoptotic bodies, microvesicles, and exosomes or bound to the RNA-binding proteins. However, the secretory mechanism and biological function, as well as the significance of extracellular miRNAs, remain largely unclear. In this article, we summarize the latest and most significant discoveries in recent peer-reviewed research on secretory miRNA involvement in many aspects of physiological and pathological conditions, with a special focus on cancer. In addition, we discuss a new aspect of cancer research that is revealed by the emergence of “secretory miRNA. ”
Shear-induced nitric oxide production by endothelial cells

We present a biochemical model of the wall shear stress (WSS)-induced activation of endothelial nitric oxide synthase (eNOS) in an endothelial cell (EC). The model includes three key mechanotransducers: mechanosensing ion channels, integrins and G-protein-coupled receptors. The reaction cascade consists of two interconnected parts. The first is rapid activation of calcium, which results in formation of calcium-calmodulin complexes, followed by recruitment of eNOS from caveolae. The second is phosphoryaltion of eNOS by protein kinases PKC and AKT. The model also includes a negative feedback loop due to inhibition of calcium influx into the cell by cyclic guanosine monophosphate (cGMP). In this feedback, increased nitric oxide (NO) levels cause an increase in cGMP levels, so that cGMP inhibition of calcium influx can limit NO production. The model was used to predict the dynamics of NO production by an EC subjected to a step increase of WSS from zero to a finite physiologically relevant value. Among several experimentally observed features, the model predicts a highly nonlinear, bipha-sic transient behavior of eNOS activation and NO production: a rapid initial activation due to the very rapid influx of calcium into the cytosol (occurring within 1 to 5 minutes) is followed by a sustained period of activation due to protein kinases.

LCGA: Local Cultivation Genetic Algorithm For Multi-objective Optimization Problems

In this paper, a new genetic algorithm for multi-objective optimization problems is introduced. That is called "Local Cultivation GA (LCGA)". LCGA has a neighborhood crossover mechanism in addition to the mechanism of GAs that had proposed in the past researches. As compared with SPEA2, NSGA-II, and MOGA, LCGA is the robust algorithm which should find the Pareto optimum solution. Since LCGA is easy to implement to parallel computer as a master-slave model, the reduction of calculation cost can be expected.
The capacity loss of uncorrelated equi-power Gaussian input over MIMO channel

We investigate the capacity loss of an uncorrelated Gaussian input with equal power (i.i.d. Gaussian input) over a multi-input multi-output linear additive noise (not necessarily Gaussian nor memoryless) channel. Previous work showed that this input is the best input in the case of Gaussian noise, assuming the channel matrix is known at the receiver but unknown at the transmitter. We show that i.i. d. Gaussian is a robust input also when the noise is not Gaussian. Specifically, we show that for n/sub t/ transmit antennas and n/sub r/ receive antennas, the capacity loss of an i.i. d. Gaussian input is smaller than min{n/sub t//2, (n/sub r//2)log/sub 2/(1 + n/sub t//n/sub r/)} bits, for any noise and channel matrix. This bound is apparently not tight. Nevertheless, for the case of Gaussian noise we derive a stronger bound which is tight for a "critical" channel matrix: (n/sub r//2)log/sub 2/(n/sub t//n/sub r/) bits for 1/spl les/ n/sub r//spl les/(n/sub t//e) and (n/sub t//2)(log/sub 2/(e))/e bits for n/sub r//spl ges/(n/sub t//e).
RAAT – The Reverie Avatar Authoring Tool A JavaScript library for designing online 3 D character creator software

avatar embodiment within the World Wide Web has gained a lot of popularity in recent years thanks t o the introduction of networked virtual environments created for socialization and entertainment purposes. As each of these virtual worlds generates a unique set of user requi rements concerning representation preferences based on the environment’s context, it becomes clear that every attempt at creating such virtual worlds should encourage the d evelopment of the appropriate avatar authoring tools, being based on a thorough study of avatar desirable features. The Rev erie Avatar Authoring Tool (RAAT) introduced in this paper helps developers address these ever-emerging avatar featu re requirements, allowing them to easily set up and de sign online character creation applications, tailored to the vi rtual environment specifications. Summarizing the design process to a simple task of documenting the application interfac e within a single script, RAAT encapsulates the demanding task of character creation within simple function calls, while also offering a web-based real-time solution for photore alistic integration of user physical appearance onto the ch aracter mesh.

A hypervisor-based system for protecting software runtime memory and persistent storage

An important goal of software security is to ensure sensitive/secret data owned by a program shall be exclusively accessible by the program. An obstacle to such security goal is that modern commodity operating systems (OS) for the sake of speed and flexibility have a unified linear address space--any OS kernel program can access all the linear addresses. As a result, rootkits or malicious system software are able to control the OS virtual address space, harvest the sensitive data used by software programs on the compromised computer, and report the data to remote entities controlled by hackers. In this paper, we present a holistic approach against sophisticated malware. Instead of focusing on the security of various abstraction layers of OS, we utilize the hardware techniques to directly provide the trust services to software programs. Without modifying OS, we leverage the virtual machine monitor technologies to create a lightweight hypervisor for fine-grain software runtime memory protection. As a result, a program's memory could be hidden from other high privilege system software in a single commodity OS. In addition, we propose the data locker component in the hypervisor, which prevents the sensitive data of software program in persistent storage from leaking to rootkits or other malware. For the performance evaluation, the implementation based on hardware-assisted x86 virtualization technology is presented and experimental results are reported.
Recent Insights into Inhibition, Structure, and Mechanism of Configuration-Retaining Glycosidases.

Not "from above", but "from the side": Configuration-retaining β-glycosidases protonate their substrate either anti or syn to the endocyclic C1-O bond as the first step in the enzymic cleavage of the glycosidic bond (see schematic drawing). Insights into the mechanism of action of glycosidases have been gained by a combination of the synthesis of inhibitors, the study of the kinetics of their inhibition, and the analysis of the crystal structures of glycosidases and glycosidase-ligand complexes.
Spermwhale population structure in the eastern and central North Pacific inferred by the use of single-nucleotide polymorphisms , microsatellites andmitochondrial DNA

We use mitochondrial DNA (mtDNA) (400 bp), six microsatellites and 36 single-nucleotide polymorphisms (SNPs), 20 of which were linked, to investigate population structure of spermwhales (Physeter macrocephalus) in the eastern and central North Pacific. SNP markers, reproducible across technologies and laboratories, are ideal for long-term studies of globally distributed species such as sperm whales, a species of conservation concern because of both historical and contemporary impacts. We estimate genetic differentiation among three strata in the temperate to tropical waters where females are found: California Current, Hawai`i and the eastern tropical Pacific. We then consider how males on sub-Arctic foraging grounds assign to these strata. The California Current stratum was differentiated from both the other strata (P < 0.05) for mtDNA, microsatellites and SNPs, suggesting that the region supports a demographically independent population and providing the first indication that males may exhibit reproductive philopatry. Comparisons between the Hawai`i stratum and the eastern tropical Pacific stratum are not conclusive at this time. Comparisons with Alaska males were statistically significant, or nearly so, from all three strata and individuals showed mixed assignment to, and few exclusions from, the three potential source strata, suggesting widespread origin of males on sub-Arctic feeding grounds. We show that SNPs have sufficient power to detect population structure even when genetic differentiation is low. There is a need for better analytical methods for SNPs, especially when linked SNPs are used, but SNPs appear to be a valuable marker for longterm studies of globally dispersed and highly mobile species.
A cooperative scheme to aggregate spatio-temporal events in VANETs

Today, thanks to vehicular networks, drivers may receive useful information produced or relayed by neighboring sensors or vehicles (e.g., the location of an available parking space, of a traffic congestion, etc.). In this paper, we address the problem of providing assistance to the driver when no recent information has been received on his/her vehicle. Therefore, we present a cooperative scheme to aggregate, store and exchange these events in order to have an history of past events. This scheme is based on a dedicated spatio-temporal aggregation structure using Flajolet-Martin sketches and deployed on each vehicle. Contrary to existing approaches considering data aggregation in vehicular networks, our main goal here is not to save network bandwidth but rather to extract useful knowledge from previous observations. In this paper, we present our aggregation data structure, the associated exchange protocol and a set of experiments showing the effectiveness of our proposal.
