Abstract

Objectives: An algorithm is proposed to allocate the scan cells to form a particular set of scan chains. The proposed algorithm reduces wire length and number of multi-voltage cells. This also maintains the balance of the chain. Methods: The proposed algorithm was implemented in Tool Command Language (TCL) and it works on the post placed database. The developed algorithm was tested on some of the industrial designs. Findings: The proposed algorithm was tested on some of the industrial designs and a reduction was observed in the scan chains wire length (about 10%) and a much greater reduction in the count of the lockup latches (about 90%). Improvements/Applications: This will ensure a reduction in congestion as well as reduced area requirements.

Abstract

This paper describes the advance techniques for object detection and tracking in video. Most visual surveillance systems start with motion detection. Motion detection methods attempt to locate connected regions of pixels that represent the moving objects within the scene; different approaches include frame-to-frame difference, background subtraction and motion analysis. The motion detection can be achieved by Principle Component Analysis (PCA) and then separate an objects from background using background subtraction. The detected object can be segmented. Segmentation consists of two schemes: one for spatial segmentation and the other for temporal segmentation. Tracking approach can be done in each frame of detected Object. Pixel label problem can be alleviated by the MAP (Maximum a Posteriori) technique.

Keywords

Abstract

Black pepper (Piper nigrum L., family: Piperaceae) is one of the oldest and most widely used culinary spices. Convention-ally leaves of black pepper plant have a single acuminate or mucronate tip¹, but we found multiple tips in some black pepper plants. Panniyur-5 is a variety bred at the Pepper Research Station Panniyur by Kerala Agricultural Univer-sity, Thrissur, India. It is a selection from open pollinated seedling progeny of Pe-rumkodi with moderate susceptibility to foot rot disease at nursery². Horticulture Section of ICAR-Central Coastal Agri-cultural Research Institute is engaged in research of black pepper as suitable inter/ mixed crop in perennial crop-based cropping systems.

Abstract

The requirement of an Open Protocol for energy metering was a long awaited and most required standard for bringing in homogeneity among various makes of meters deployed in the fi eld by the Power utilities. The openness of the standard will make the Automatic Meter Reading (AMR) and interoperability into reality. This open protocol based on IEC-62056 (DLMS/COSEM) helps to overcome most of the challenges for data acquisition for the utilities. The Indian Companion Specifi cation (ICS) was evolved by BIS as an Indian Standard IS-15959 which inherits the IEC-62056 series of standards. This paper brings out the advantages of ICS and tests being performed for compliance.
