Internet of Things (loT) aims at collecting data from billions of devices connected altogether. Despite there is no one technology able to cope with all possible scenarios, LPWAN solutions are emerging as viable technologies for implementing private, low-cost cellular like wireless networks. Distributed systems could leverage this approach as a driving technology for services as smart environment...
Cognitive radio (CR) sense the spectrum to discover the available white spaces in it for making better utilization of spectrum and alleviates the spectrum shortage problem. While using the available spectrum, it avoids the harmful interference with licensed users or primary users (PUs). Individual spectrum sensing by CR may not be accurate due to fading and shadowing effects. Cooperative spectrum...
Thin-film technology is a low cost technology for electronic semiconductor devices and optical devices. Thin films are emerging technology for low cost PV applications. Thin film solar cells can be fabricated on glass substrate by close spaced sublimation (CSS) process for very low cost approach. In this work it has been designed and implemented a prototype CSS chamber for fabricating thin films by...
Phishing is a criminal scheme to steal the user's personal data and other credential information. It is a fraud that acquires victim's confidential information such as password, bank account detail, credit card number, financial username and password etc. and later it can be misuse by attacker. We aim to use fundamental visual features of a web page's appearance as the basis of detecting page similarities...
Accelerator control system is the core of the accelerator. Laboratory physics and industrial control system (Epics) is jointly developed by the United States Los Alamos National Laboratory (LANL) and Argonne Laboratory (ANL) control system integration tool, which is widely used in the accelerator control system. EPICS control system has the advantages of openness, practicality, and reliability. In...
Orthogonal Frequency Division Multiplexing (OFDM) signals suffer from high PAPR (Peak to Average Power Ratio). Cyclic shifted sequences (CSS) was proposed as a solution to high PAPR. CSS reduces PAPR stochastically by giving some independent cyclic shifts to the time-domain signals of clusters. In CSS, however, we must transmit side information (SI) regarding the cyclic shift. Although a blind method...
Cross-site scripting (also referred to as XSS) is a vulnerability that allows an attacker to send malicious code (usually in the form of JavaScript) to another user. XSS is one of the top 10 vulnerabilities on Web application. While a traditional cross-site scripting vulnerability exploits server-side codes, DOM-based XSS is a type of vulnerability which affects the script code being executed in the...
In this demo, we present an online code editor that dynamically identifies and patches simple modifications in the source code of a Web document containing time-based elements (e.g., CSS3 and SVG animations, HTML5 audio and video) without the need to restart the playback of the whole document from the beginning. We hope that the functionalities shown in this demo can make learning to code more attractive.
The aim of this study is to make simulations with Matlab/Simulink to be used in the production phase of the autoclave in the sterilization unit. Sterilization unit is very important in terms of hospital employees and patients for protecting from infections and accidents. The study examined autoclave equipments that are fabricated based on the EN standards, then mathematical calculations were performed...
Cascading style sheets (CSS) is a language that describes the presentation of web documents. CSS is widely adopted in web development and it is now common for web projects to have several thousands of CSS lines of code. Because the language lacks advanced features to allow code reuse, several languages such as Sass and Less have emerged as extensions to CSS. They provide mechanisms such as mixins...
Programmable logic controller (PLC) has been used for the development of data acquisition and control (DAC) system for 45.6 MHz, 100 kW ICRH system using EPICS. DAC can monitor and acquire 16 digital inputs, 16 analog outputs, 16 digital outputs and 32 analog inputs signals. Graphical user interface (GUI) has been developed using JAVA based control system studio (CSS) on eclipse platform. WebOPI module...
Close spaced sublimation (CSS) has attractive features for high-rate deposition of CdS/CdTe thin film solar modules. It is necessary to have a solid growth model to explain their growth. In past 20 years, there are several growth models which are conflict each other. In this paper, a growth model was developed for CdTe deposition. The model can explain the effect of source and substrate temperature,...
Nowadays high energy physics scientists build and design systems that are complex in terms of the huge amount of subsystems and individual components. A single subsystem may consist of a few tens of thousands digital and analogue channels and sensors. As a result, the data rates captured in modern systems may result in gigabytes per second. Complex systems could generate various alarms and provide...
A broad range of emerging applications require very low power, very long range yet low throughput communication. Different standards are being proposed to meet these novel requirements. In this paper, the technical differences between a wideband spread spectrum (LoRa-like) and an ultra narrowband (Sigfox-like) network will be explained and evaluated. On the physical layer, simulation results show...
A recent huge interest in Machine to Machine communication is known as the Internet Of Things (IOT), to allow the possibility for autonomous devices to use Internet for exchanging the data. The Internet and the World Wide Web have caused a revolution in communication between the people. They were born from the need to exchange scientific information between instrumentation. Control System Studio (CSS)...
Ideation and innovation can be supported by more or less formalized creativity methods such as brainstorming or morphological analysis. While previous studies have shown increased productivity with computer-supported versions of such methods, their paper-based variants still largely prevail because of non-performance-related factors. We conducted a study with 23 well-motivated and creative participants...
This paper presents the description of a project to develop an accessible indoor plan to help blind people to localize landmarks within a building from a pedagogical perspective. This project has been employed to foster engineering students to acquire the necessary knowledge and skills to use technologies and tools to develop accessible engineering products within the context of a collaborative learning...
Spectrum sensing is the most appropriate method performed by cognitive radio for the efficient utilization of RF spectrum without any harmful interference to the primary users. In this paper, we propose various spectrum sensing technique. Based on spectrum sensing, cooperative sensing is done over various spectrum sensing technique to overcome the problem of miss detection and false alarm which is...
HTML5 [1] has been recently evolution in web technologies which enables user to create web based control system user interfaces (UI). These user interfaces can work on cross browser and cross device compatible. Control system studio (CSS) Operator Interfaces (OPI) allow user to create user interfaces with drag and drop fashion. These developed interfaces developed in CSS BOY[2] can be seamlessly display...
We report ou characterization of SnS thin films grown by high temperature close space sublimation (CSS) method. The CSS grown films are slightly Sn-rich and show high degree of crystalmity with orthorhombic (Herzeubergite) crystal structure. The as deposited SnS has direct transition at about 1.3 eV with a very high absorption (α ∼104 cm−1) in risible light range. Hall measurements in Van der Pau...
