ITH THE CONTINUED INTEREST in a u d i o c i r cu i t r y a n d d e s i g n , i t h a s b e c o m e w o r t h w h i l e f o r t h e a u d i o engineer to re-examine some of the procedures that formerly were taken largely for granted. Among these procedures is the use of the by-pass capacitor in a Class A push-pull output stage. The purpose of this capacitor seems evident enough, yet the engineer...

We prove that a particular pushing-blocks puzzle is intractable in 3D. The puzzle, inspired by the game PushPush, consists of unit square blocks on an integer lattice. An agent may push blocks (but never pull them) in attempting to move between given start and goal positions. In the PushPush version, the agent can only push one block at a time, and moreover, each block, when pushed, slides the ...

We prove that two pushing-blocks puzzles are intractable in 2D. One of our constructions improves an earlier result that established intractability in 3D [OS99] for a puzzle inspired by the game PushPush. The second construction answers a question we raised in [DDO00] for a variant we call Push-1. Both puzzles consist of unit square blocks on an integer lattice; all blocks are movable. An agent...

[1] A sensitivity analysis reveals that large uncertainty exists in estimates of solute retardation factor R made from sorption push-pull tests. A simplified push-pull data interpretation method for estimating instantaneous linear sorption in confined aquifers is developed. The new method is less restrictive in its application than the conventional method that uses an approximate analytical sol...

1.0 Introduction The million-dollar question for any production manager today is the selection between a push and a pull production system. Push and pull systems determine when and where to move material in a production process. A push system is characterized by a make to stock environment and a pull system is characterized by make to order. An appropriate system that would cater to the require...

Due to multiple-factors, bracketed popularly in ‘push-pull’ category, migration, both internal and external, is taking place in Bangladesh. In Bangladesh, the dominant form of migration is from rural to urban centers. For, Bangladesh is predominantly an agrian rural society for 80.0 percent of the total population lives in 87319 villages. The urban centers of Bangladesh are developing rapidly a...

Am ajor problem ofe-commerce is the high rate of customer initiated abortions of processes. It may be solved by the implementation of a Push System that supports the webshop. One major module of the Push System is the Pushflow Manager that proactively l eads customers through their processes by taking over tasks or triggering following activities. Its theoretical background, the Push Concepts, ...

School bullying is a serious problem among teenagers, causing depression, dropping out of school, or even suicide. It is thus important to develop antibullyingmethods.This paper proposes a physical bullying detectionmethod based on activity recognition. The architecture of the physical violence detection system is described, and a Fuzzy Multithreshold classifier is developed to detect physical ...
