a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...

ARM-family processors are positioned among the leaders in key embedded applications. Many presentations and short lectures have already addressed the ARM’s applications and capabilities. In this introduction, we intend to discuss the ARM’s instruction set uniqueness from the performance prospective. This introduction is also trying to follow the approaches established by two outstanding textboo...

We propose, ‘E la carte’, an eMenu solutions employing ARM architecture is proposed for next generation dining experience. eMenu is an efficient way of catering patrons thus enriching their dining experience. The implemented design results in a decrease in the customer service time of 44% and the customer downtime by 64% .A helical antenna of gain approx 7 db is designed to provide wireless tra...

ARMSim# is a simulator for the ARM architecture intended for use in both teaching and research. The simulator provides some standard features found in debuggers such as breakpoints, singlestep execution and watch-points. Its innovative features include support for software plug-ins which can implement external devices and new instructions. Such plug-ins can be used to prepare students for worki...

Acorn – the Beginning The year was 1979. Atari introduced a coin-operated version of Asteroids. The programming language ADA was born. 3COM, Oracle, and Seagate were founded. TI entered the computer market. Hayes marketed its first modem, which became the industry standard for modems. The Motorola 68K and Intel 8088 were released. And Hermann Hauser and Chris Curry, with the support of a group ...

The Achilles tendon (AT) moment arm is an important determinant of ankle moment and power generation during locomotion. Load and depth-dependent variations in the AT moment arm are generally not considered, but may be relevant given the complex triceps surae architecture. We coupled motion analysis and ultrasound imaging to characterize AT moment arms during walking in 10 subjects. Muscle loadi...

Current treatment of unilateral breast cancer-related lymphedema (BCRL) is only directed to the afflicted arm. Near-infrared fluorescent imaging (NIRF) of arm lymphatic vessel architecture and function in BCRL and control subjects revealed a trend of increased lymphatic abnormalities in both the afflicted and unafflicted arms with increasing time after lymphedema onset. These pilot results show...

Brain can be considered as a system that generates motor commands for a given perception. Understanding how movement is generated and controlled still represents unanswered questions [7]. In [3], an arm controller that learns visuo-motor associations can let emerge immediate and deferred imitation. Visual input activates some attractors in the motor space that are used to generate a speed comma...

This paper presents an approach to robot arm control based on exploiting the dynamical properties of a simple oscillator circuit coupled to the joints of an arm. Using the same architecture, a wide variety of tasks can be achieved without any explicit modeling of the arm or its environment. The inherent properties of the oscillators give robustness to perturbations and changes in frequency. The...

In this paper a discrete competitive neural network is introduced to calculate the optimal robot arm movements for processing a considered commitment of tasks, using the branch and bound methodology. A special method based on the branch and bound methodology, modified with a travelling path for adapting in the neural network, is introduced. The main neural network of the system consists of diff...
