this paper presents a REST-compliant service oriented architecture of a web-based heterogeneous wireless sensor network monitoring system that has applicability in remote patient monitoring in healthcare. As smartphone and web-page technologies are ubiquitous nowadays, our architecture uses smartphone as a gateway between the data collected and the Internet. the system uses a heterogeneous WSN consisting of environmental sensors, medical sensors, and smartphone's internal sensors. To validate the system, a prototype experiment of the system is implemented using Android smartphone platform, Crossbow Micaz motes, and Alive Technology hart and activity monitor sensor.

the practical applicability of brain-computer interface (BCI) technology is limited due to its insufficient reliability and robustness. One of the major problems in this regard is the extensive variability and inconsistency of brain signal patterns, observed especially in electroencephalogram (EEG). this paper presents a fuzzy logic (FL) approach to the problem of handling of the resultant uncertainty effects. In particular, it outlines the design of a novel type-2 FL system (T2FLS) classifier within the framework of an EEG-based BCI, and examines its on-line applicability in the presence of short-and long-term nonstationarities of spectral EEG correlates of motor imagery (imagination of left vs. right hand movement). the developed system is shown to effectively cope with real-time constraints. In addition, a comparative post hoc analysis has revealed that the proposed T2FLS classifier outperforms conventional BCI methods, like LDA and SVM, in terms of the maximum classification accuracy (CA) rates by a relatively small, yet statistically significant, margin.

We present binding properties of biomolecules and their dependence on ionic strength and temperature using a microfluidic aptameric graphene field-effect transistor (FET) nanosensor. Aptamer-immobilized graphene is used to recognize target molecules, and the resulting changes in graphene conductance is measured to study the binding kinetics of biomolecules. Binding properties of aptamer-protein interactions at different ionic strength and temperature are investigated, yielding insight into the pharmacologic basis of biomolecular recognition.

In Web-based applications, most user interactions take the form of navigating between Web pages. the structure of the navigation model thus has a strong impact on a Web application's usability. However, specifying a user-friendly navigation model for complex applications can be time-consuming, especially when designing for multiple presentation channels. We therefore present the formal semantics of the dialog flow notation (DFN) that provides constructs for the design of modular navigation models, and especially focus on constructs that reduce the specification redundancy within and between channels, thus reducing the design effort for Web-based user interfaces

Power conditioning circuits based on high breakdown voltage silicon MESFETs are being developed as an alternative to existing approaches that use CMOS or bipolar transistors. Results are presented from simulations of a low drop out (LDO) regulator as an example of the Si-MESFET technology. the LDO regulator exploits the depletion mode behavior of an n-channel MESFET to achieve low drop out voltages with impressive power supply rejection. the high voltage compliance of the Si-MESFETs (5-50V) make them ideally suited for a wide range of commercial and defense related LDO regulator applications.

Refactoring is the process of changing the structure of code without changing its behavior. Refactoring can be semi-automated with tools, which should make it easier for programmers to refactor quickly and correctly. However, we have observed that many tools do a poor job of communicating errors triggered by the refactoring process and that programmers using them sometimes refactor slowly, conservatively, and incorrectly. In this paper we characterize problems with current refactoring tools, demonstrate three new tools to assist in refactoring, and report on a user study that compares these new tools against existing tools. the results of the study show that speed, accuracy, and user satisfaction can be significantly increased. From the new tools we induce a set of usability recommendations that we hope will help inspire a new generation of programmer-friendly refactoring tools.

In SPECT (single photon emission computed tomography) and X-ray CT, point sources are commonly used to acquire data for imaging parameter estimation. the parameters are estimated by fitting the point source projection data to a mathematical model of the imaging system. this paper introduces two backprojection-based parameter estimation methods. In the first method a point source is attached to the object; the second method is data-based without using a point source at all.

the locator/identifier separation paradigm is widely considered to be a feasible solution to the problematic issues of today's Internet architecture. this approach, however, introduces a novel problem by revealing a node's location information to all of its peers. thus, each node becomes trackable. To overcome this problem, a solution is required which is able to hide location information while not limiting connectivity at the same time. So far, few proposals have been made to address this problem. In this paper, the concepts are analyzed and evaluated based on the costs introduced to the network due to overhead. the paper shows the overall costs for a privacy solution and the importance to implement mechanisms to limit additional required transit traffic.

this paper posits an automatic handling to some of the most common RTL critical issues in the verification process. In this paper, we propose an automatic linting tool to handle some causes of intentional latches generated in the synthesis process and clock gating timing violation. therefore, no need to waste verification time to dive through long codes to handle them manually. the proposed tool has been implemented using python to speed up the linting process with easy GUI. Finally, it has been tested on OpenCore certificated projects source codes.
