The ultra-wide band passive RFID system is receiving a great consideration for the researchers with the aim of substituting the conventional barcode system. The dimension of the chipless tag still rests as a big question that makes the use of tagging the object difficult as well as costly. Different backscattered signal with time delay can successf

Sodium morpholine-4-carbodithioate and four metal complexes were synthesized and characterized using various physico-chemical techniques. The ligand behaved as a uninegatively charged bidentate ligands upon complexation with metal ions with the general formula of Ma(SS)2 and Mb(SS)3, where Ma is Cu(II) and Ni(II) and Mb is Co(III) and Fe(III). All

This paper highlights the contributions of ordinary citizens to the development of a developing country – Bangladesh. The article discusses the contributions made by two ordinary citizens of Bangladesh, Begum Rokeya Sakhawat Hossain and Khondker Azizur Rahman Salim, toward building the society. It is argued in this paper that the participation of

We introduce an analytical technique to solve strongly nonlinear oscillators with cubic and harmonic restoring force by using harmonic balance method (HBM). A set of nonlinear algebraic equations is appeared when HBM is imposed. In this paper, a power series solutions of these nonlinear algebraic equations gives desired results and to avoid numeric

A resonator type chipless RFID tag comprised of two separate antennas, one transmission line with spiral resonators. The key element of a chipless RFID tag is its passive spiral microstrip resonator circuit which contains the data bits for the tag. To decrease the dimension of resonator in chipless tag is still challenging task. At present rectangu

It is argued in this paper that although the South Asian sub-continent was split into two independent states of Pakistan and India in 1947 on the basis of religion, in the post-independence years, in both states the question of national language emerged as a major issue in their national politics, and threatened to reshape their religion-based nati

Even though the UWB passive RFID is getting so much attention for the researchers with the goal of replacing the conventional barcode system, the tag dimension still remains as a big issue which makes the tag price comparatively higher than the barcode. Many proposals have been made for last one decade to overcome this problem. In this paper an app

Composition of atherosclerotic arterial walls is rich in lipids such as cholesterol; unlike normal arterial walls. In this study, we aimed to utilize this difference to diagnose atherosclerosis via multispectral imaging, which allows for identification of fluorescence originating from the substance in the arterial wall. The inner surface of extract

A biography may be defined as “our non-fictional output devoted to recording and interpreting real lives” (Hamilton 1). Biographies generally range along a continuum from scholarly to popular to super-pop. Redoubtable Reformer: The Life and Times of Cheah Cheang Lim is a biography with a difference. It does not fall into any of the categories o

Introduction: Hypertension is having an increasing impact on the world population’s morbidity and mortality. The pathogenesis of hypertension is multifactorial but the ‘adrenaline hypothesis’ is being increasingly identified as a cause for hypertension in the young. Objective: The aim of this study is to assess the extent and sustainability o
