A. Saberkari, S. B. Shokouhi,

In this paper, an imaging chip for acquiring range information using by 0.35 μm CMOS technology and 5V power supply has been described. The system can extract range information without any mechanical movement and all the signal processing is done on the chip. All of the image sensors and mixed-signal processors are integrated in the chip. The design range is 1.5m-10m with 18 scales.

در این پایان نامه، الگوریتمی جدید برای جداسازی کور منابع غیر ایستان و باند وسیع در شبکه های حس گر بی سیم ارایه می کنیم. این منابع، در حوزه زمان-فرکانس دارای انرژی متمرکز هستند. از جمله این منابع می توان به سیگنال های fm اشاره کرد. در کاربردهایی نظیر رادار، سونار و مسایل آکوستیکی زیرآبی، به کرات با چنین سیگنال هایی مواجه می شویم. از آن جایی که تحلیل زمان- فرکانس در پردازش سیگنال، دارای اهمیت بسی...

A classification technique using Support Vector Machine (SVM) classifier for detection of rolling element bearing fault is presented here.  The SVM was fed from features that were extracted from of vibration signals obtained from experimental setup consisting of rotating driveline that was mounted on rolling element bearings which were run in normal and with artificially faults induced conditio...

Recently, blind multi-user detection has become an important topic in code division multiple access (CDMA) systems. Direct-Sequence Spread Spectrum (DSSS) signals are well-known due to their low probability of detection, and secure communication. In this article, the problem of blind multi-user detection is studied in variable processing gain direct-sequence code division multiple access (VPG D...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...
