Modeling 3D IC structures with through-silicon vias (TSVs) is a promising technique to achieve "more than Moore" integration. Carbon nanomaterials are an emerging solution due to its properties like high thermal conductivity and better ampacity. In this paper, Carbon nanotube (CNT) and copper composite as TSV and Graphene nanoribbons (GNRs) as interconnects are considered to improve the performance of 3D ICs. A comparison of the electro-thermal behavior of copper, CNT and copper-CNT composite is shown in this work. The electrical resistance is less than CNT by 57.3% and 72.9% in case of copper-CNT composite and copper respectively. The CNT/GNR interface and copper-CNT/GNR interface offers 80.5% and 64.2% lower interface resistance than its copper counterpart. The thermal conductivity obtained by copper-CNT composite is better than copper because self-heating effects are eliminated to a large extent. The Cu-CNT composite provides a better electrical conductivity than CNT and better thermal conductivity than copper thus providing a tradeoff between the two alternative TSV configurations.

Different types of signals are frequently encountered in different fields of science and engineering. A wide range of signal processing techniques have been developed to utilize those signals in different fields. This often requires peak-detection of a signal which has been done by applying different techniques. This paper presents a simple algorithm for peak-detection of a signal using concept of half-wave rectification of signal followed by R-load and C filtering. Instead of constructing actual circuit, this paper uses only its simple mathematical modeling and also avoids any complicated calculation procedure. The complete algorithm is validated via simulation in a digital platform and via experimentation, using an inexpensive mid-level 8-bit fixed-point processor.

Micro-grid integrates the different distributed renewable energy resources such as solar, wind, and biomass. It can operate either in the stand-alone condition or in synchronization with the utility grid. Extensive research is being done on the implementation of SCADA systems for micro-grids that perform efficiently and are cost-effective. The development of effective and cost-effective real-time data acquisition and remote monitoring systems for micro-grid is essential to study the generated and consumed power quality measurement, stability, reliability, and maintenance optimization. Incomplete data and inaccurate measurement of energy output can lead to false conclusions and lost revenue. In this work, we have used Raspberry Pi for data communication and remote monitoring in a solar-wind-biogas integrated micro-grid system. Data acquisition has been done from smart meters of Elite 440-443 series of Secure Pvt. Ltd. Once the data comes to Raspberry Pi it has been used for different purposes like data display, warnings as parameters go off-limit and online remote monitoring. The operation, results and future scope of the developed data communication and remote monitoring system have been studied and analyzed in detail.

Output power of Solar PV modules is significantly dependent on optical properties of the glass cover which may start degrading due to dust deposition on its surface from its very first day of installation. As dust concentration in atmosphere varies over different seasons, it causes variation of dust accumulation and also the optical properties of module glass cover. A dust chamber has been developed designed and fabricated in the laboratory to assess the change in optical properties (transmittance, reflectance and absorbance) of glass with respect to the amount of Shibpur roof-top dust accumulated on it. Experiment shows that transmittance due to dust deposition reduces from 85% to 35% depending on the deposited amount. From the study of PV power plant of IIEST, Shibpur, it is seen that dust deposition is the highest during spring. Similar results are also observed in two running PV power plants in Kolkata.

In this paper, the output voltage of a DC-DC boost converter with pulse-width modulator (PWM) has been controlled using an output feedback H-infinity (H∞) controller. The H∞ controller for the converter has been designed applying the concept of Linear Matrix Inequality (LMI) technique. The main target of this study is to regulate the output voltage of the non-linear boost converter in presence of parameter variations and external noise. The designed H∞ controller regulates different reference voltages in presence of sensor noise and parameter variations. The proposed H∞ controller is also very simple and does not require any inner current loop with the outer voltage loop like the other designed controller reported earlier.

The globalised nature of design and manufacturing process of Integrated Circuits (ICs) makes them susceptible to malicious alterations called Hardware Trojan Horses (HTH). Prior estimation of degree of vulnerability of internal nets of an IC is therefore a valuable measure to ensure its security. An improved testability measurement process has been suggested by this paper, which effectively assesses the vulnerability of the internal nets to HTH insertion. The evaluated vulnerability measures can be used to generate test patterns, which in turn helps detect the presence of HTH in the IC.
