High-performance muscles such as the shaker muscles in the tails of western diamond-backed rattlesnakes (Crotalus atrox) are excellent systems for studying the relationship between contractile performance and metabolic capacity. We observed that shaker muscle contraction frequency increases dramatically with growth in small individuals but then declines gradually in large individuals. We tested...

Supplier selection and material procurement planning are the most important issues in supply chain management. This decision is complicated when the buyers face with discount price schemes. In real situation, each supplier may apply different methods such as different types of discount schedules and various types of payment in order to increase market share. In this situation, buyers try to sel...

The problem of covert communication over Multiple-Input Multiple-Output (MIMO) Additive White Gaussian Noise (AWGN) channels is investigated, in which a transmitter attempts to reliably communicate with legitimate receiver while avoiding detection by passive adversary. capacity the MIMO AWGN characterized under variational distance covertness constraint when channel matrices are static and know...

In this paper, an algorithm is proposed to improve the Maximum Load Carrying Capacity (MLCC) of exible robot manipulators. The maximum allowable load which can be achieved by a exible manipulator along a given trajectory is limited by the joints' actuator capacity and the end e ector accuracy constraint. In an open-loop approach, the end e ector deviation from the prede ned path is signi cant a...

Information embedding on actions is a new channel model in which a specific decoder is used to observe the actions taken by the encoder and retrieve part of the message intended for the receiver. We revisit this model and consider a different scenario where a secrecy constraint is imposed. By adding a wiretapper in the model, we aim to send the confidential message to the receiver and keep it s...

This paper is dedicated to a study of different extensions of the classical knapsack problem to the case when different elements of the problem formulation are subject to a degree of uncertainty described by random variables. This brings the knapsack problem into the realm of stochastic programming. Four different model formulations are proposed, based on the introduction of probability constra...

We consider a wireless cellular network serving streaming traffic. We study in this context the effect of the users mobility on their quality of service (QoS). If the arrival of a new user violates the capacity constraint, then his call is blocked. If the user is first admitted but the capacity constraint is violated later when he attempts to move, then his call is dropped. The blocking and dro...

Constrained coding is used widely in digital communication and storage systems. In this paper, we study a generalized sliding window constraint called the skip-sliding window. A skip-sliding window (SSW) code is defined in terms of the length L of a sliding window, skip length J , and cost constraint E in each sliding window. Each valid codeword of length L+kJ is determined by k+1 windows of le...

We show that when a supply channel is capacity-constrained and the constraint is tight, there is a set of linear wholesale price contracts that coordinates the channel while allowing the supplier to make a profit. We prove this for the one-supplier/one-newsvendor supply channel as well as the many-supplier/one-newsvendor channel configuration (with each supplier selling a unique product). We an...
