Chirp signals occur naturally in different areas of signal processing. Recently, Kundu and Nandi [6] considered the least squares estimators of the unknown parameters of a chirp signal model and established their consistency and asymptotic normality properties. It is observed that the dispersion matrix of the asymptotic distribution of the least squares estimators is quite complicated. The aim ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015211784 DESCRIPTION A 64-year-old diabetic Caucasian man presented with progressively worsening neurological symptoms including memory loss, involuntary teeth clenching, difficulty maintaining balance, daytime somnolence and cognitive impairment for the past 2 years. Nine months...

Background: Cutaneous metastases can occur in a wide variety of internal malignancies and may be the first sign of a clinically silent visceral cancer. Study Design: A retrospective analysis was made of 138 cases diagnosed with cutaneous and subcutaneous metastasis on fine-needle aspiration cytology (FNAC). Primary tumors of the skin/subcutis were excluded. Results: Of 138 cases, the primary wa...

The gamma and Weibull distributions are commonly used for analyzing any lifetime data or skewed data. Recently a new family of generalized exponential (GE) distributions was introduced and studied quite extensively by Gupta and Kundu in series of papers. In this talk we show that many properties of this new family are quite similar to those of a gamma family. Since the GE distribution function ...

Endüstri devrimiyle birlikte artan üretim faaliyetleri, görsel ve yazılı medyanın etkisiyle toplumda tüketim anlayışının değişmesine neden olmuştur. Gereksinimin ötesinde arzu, hayal belki de ütopyalara ulaşmayı sağlayan bir tatmin yolu olarak görülmeye başlanan tüketim, simgesel sembolik boyut kazanmış, simülasyon gerçeklik ayrımı ortadan kalkmıştır. Toplum hayatında meydana gelen bu gelişmele...

Monogamy inequalities for the way bipartite Einstein-Podolsky-Rosen (EPR) steering can be distributed among N systems are derived. One set of inequalities is based on witnesses with two measurement settings, and may be used to demonstrate correlation of outcomes between two parties, that cannot be shared with more parties. It is shown that the monogamy for steering is directional. Two parties c...

In this chapter, the authors study the performance of Cooperative Spectrum Sensing (CSS) with soft data fusion, given by Maximal Ratio Combining (MRC)-based fusion with Weibull faded channels, and Lognormal shadowed channels. More precisely, they evaluate the performance of a MRC-based CSS with Cognitive Radios (CRs) censored on the basis of the quality of the reporting channels. The performanc...

The paper addresses the problem of finding top k influential nodes in large scale directed social networks. We propose two new centrality measures, Diffusion Degree for independent cascade model of information diffusion and Maximum Influence Degree. Unlike other existing centrality measures, diffusion degree considers neighbors’ contributions in addition to the degree of a node. The measure als...

We explore methods to use thermostatically controlled loads (TCLs), such as water heaters and air conditioners, to provide ancillary services by assisting in balancing generation and load. We show that by adding simple imbedded instructions and a small amount of memory to temperature controllers of TCLs, it is possible to design open-loop control algorithms capable of creating short-term pulses...
