The present paper describes Simultaneous Switching Noise (SSN) suppression by means of a novel electromagnetic band gap (EBG) structure. The proposed method is shown to be an alternative to the use of decoupling capacitors which usually requires many vias and the mitigation level noise is not sufficient for frequencies above the MHz range as well as standard Power/Ground (PWR/GND) plane segmentation. It is demonstrated how noise mitigation can be achieved over a wide-band frequency range (including low frequency) using a two dimensional (2D) EBG structure. The novelty of the proposed design is represented by the total absence of shorting vias. SSN suppression is analyzed by means of numerical simulations based on the Finite Integration Technique (FIT). The impact of the design on the signal integrity for signal referring to PWR plane is also investigated both in time domain (eye-diagrams) and frequency domain (S-parameters).

Problem Solving skills are very important to facilitate students in understanding and solving mathematical problems and in everyday life. But what is often found is low student problem solving skills, and even Indonesian students' PISA math results are ranked low. This study aims to: (1) describe the process of developing Islamic-based PISA model questions on content quantity and enrichment to improve students' problem solving skills;(2) describe the results of the development of Islamic-based PISA model problems on topics concerning Quantity and enrichment in a valid and practical manner;and (3) reveal the improvement of students' problem solving skills after applying the Islamic-based PISA model questions on the content quantity and enrichment. The research subjects were students of class VIII-A MTs Plus Baitussalam Toyamas, Banyuwangi regency in the even semester of the 2018/2019 academic year. The research design used two stages, namely the preliminary stage and formative evaluation. The stages of formative evaluation include the stages of self evaluation, prototyping (expert review, one-to-one, and small groups), and field tests. The research instrument used was a validation sheet;Observation sheet and student response questionnaire, and student learning outcomes test. Data analysis techniques include data analysis process development questions, validity, reliability, and problem solving skills of students. The question development design consists of two stages, namely preliminary and formative evaluation. The formative evaluation stage includes self evaluation, prototyping (expert review, one-to-one, and small groups), and field tests. The results showed that the development of a prototype device produced 10 items of Islamic-based PISA mathematical problems that were valid and practical. The results of the prototype validation test have validity values above 0.361 and the results from the table show r-count> r-table so that the questions have high reliability,

Two related physical phenomena have recently been observed: quantum states of neutrons in the gravitational field above a flat mirror, and quantum states of neutrons in an effective centrifugal potential in the vicinity of a concave mirror. It is curious that the measurement of the near-surface quantum states of these two types is the first direct demonstration of the weak equivalence principle for a massive object in a quantum state. These two phenomena and their application to various domains of science will be explored using a new GRANIT spectrometer, which is under commissioning in the Institut Laue-Langevin, Grenoble, France. Most recent advances in these domains are mentioned.

This paper presents a deeper insight into the present need of the Carbon Nano Tube Field Effect Transistor (CNTFET) by its comparison with conventional MOSFET for digital applications. Here, one-single walled-32nm long-tube CNTFET technology has been considered as base and compared with 45nm, 32nm & 22nm CMOS technologies by implementing a digital inverter. Various parameters in current & voltage analysis have been compared through HSPICE simulations which indicate higher performance of CNTFET over the CMOS technology and the limitations of latter upon scaling down to 22nm technology node. However, deeper examination reveals an issue of short-circuit current transients in case of CNTFET inverter that must be prevented at nano regime.
