Commodity Exchanges and the Privatization of the Agricultural Sector in the Commonwealth of Independent States—Needed Steps in Creating a Market Economy

Pre-revolutionary commodities exchanges in Russia and their extinguishment by the Bolsheviks are examined, and the role thereafter by Soviet central planners in the distribution, import and export of agricultural commodities is described. It is argued that the privatization process in the CIS must include incentives for the development of an exchange system for agricultural goods

Power and Identity in Three Gothic Novels: \u3ci\u3eThe Mysteries of Udolpho\u3c/i\u3e, \u3ci\u3eCaleb Williams\u3c/i\u3e, and \u3ci\u3eMelmoth the Wanderer\u3c/i\u3e.

Abstract This study examines the connection between power and identity in three Gothic novels, Ann Radcliffe’s The Mysteries of Udolpho, William Godwin’s Caleb Williams, and Charles Robert Maturin’s Melmoth the Wanderer. Following the identity theories of Erik Erikson, I argue that identity has biological, psychological, and social aspects that are subject to change over time. As individual agency—the ability to function as a person—depends on a relatively certain and stable sense of personal identity, Gothic villains—both individuals and institutions—gain and maintain their power by disempowering their victims. In order to do so, they work to compromise these victims’ sense of personal identity, causing them to suffer identity crises that greatly reduce their ability to function. Employing various means—including threats of rape, destruction of reputation, imprisonment, forced exile, denial of freedom of thought, torture, and others—Gothic villains attempt to weaken their victims by placing them in situations that cause the fears that Erikson argues all people share to become paralyzing and debilitating states of anxiety, states in which the victims suffer from a temporary, or, in extreme cases, permanent loss of agency. These Gothic victims’ paranoia, identity crises, and subsequent loss of agency underscore the importance of individuals’ identity and constitute the horror that is at the heart of Gothic fiction

Walking Stabilization Using Step Timing and Location Adjustment on the Humanoid Robot, Atlas

While humans are highly capable of recovering from external disturbances and uncertainties that result in large tracking errors, humanoid robots have yet to reliably mimic this level of robustness. Essential to this is the ability to combine traditional "ankle strategy" balancing with step timing and location adjustment techniques. In doing so, the robot is able to step quickly to the necessary location to continue walking. In this work, we present both a new swing speed up algorithm to adjust the step timing, allowing the robot to set the foot down more quickly to recover from errors in the direction of the current capture point dynamics, and a new algorithm to adjust the desired footstep, expanding the base of support to utilize the center of pressure (CoP)-based ankle strategy for balance. We then utilize the desired centroidal moment pivot (CMP) to calculate the momentum rate of change for our inverse-dynamics based whole-body controller. We present simulation and experimental results using this work, and discuss performance limitations and potential improvements

Never mind the iPhone X, battery life could soon take a great leap forward

First paragraph: Another suite of Apple iPhones, another media frenzy. Much has been written about the $999/£999 iPhone X, the demise of the home button, the “face ID” function, wireless charging and so on. Somewhere down the list of improvements was extra battery life, at least for the iPhone X, thanks to its new souped up A11 bionic processor

Straight-Leg Walking Through Underconstrained Whole-Body Control

We present an approach for achieving a natural, efficient gait on bipedal robots using straightened legs and toe-off. Our algorithm avoids complex height planning by allowing a whole-body controller to determine the straightest possible leg configuration at run-time. The controller solutions are biased towards a straight leg configuration by projecting leg joint angle objectives into the null-space of the other quadratic program motion objectives. To allow the legs to remain straight throughout the gait, toe-off was utilized to increase the kinematic reachability of the legs. The toe-off motion is achieved through underconstraining the foot position, allowing it to emerge naturally. We applied this approach of under-specifying the motion objectives to the Atlas humanoid, allowing it to walk over a variety of terrain. We present both experimental and simulation results and discuss performance limitations and potential improvements.Comment: Submitted to 2018 IEEE International Conference on Robotics and Automatio

Search-based energy optimization of some ubiquitous algorithms

Reducing computational energy consumption is of growing importance, particularly at the extremes (i.e. mobile devices and datacentres). Despite the ubiquity of the JavaTM Virtual Machine (JVM), very little work has been done to apply Search Based Software Engineering (SBSE) to minimize the energy consumption of programs that run on it. We describe OPACITOR , a tool for measuring the energy consumption of JVM programs using a bytecode level model of energy cost. This has several advantages over time-based energy approximations or hardware measurements. It is: deterministic.  unaffected by the rest of the computational environment.  able to detect small changes in execution profile, making it highly amenable to metaheuristic search which requires locality of representation. We show how generic SBSE approaches coupled with OPACITOR achieve substantial energy savings for three widely-used software components. Multi-Layer Perceptron implementations minimis- ing both energy and error were found, and energy reductions of up to 70% and 39.85% were obtained over the original code for Quicksort and Object-Oriented container classes respectively. These highlight three important considerations for automatically reducing computational energy: tuning software to particular distributions of data; trading off energy use against functional properties; and handling internal dependencies which can exist within software that render simple sweeps over program variants sub-optimal. Against these, global search greatly simplifies the developer’s job, freeing development time for other tasks

Metaheuristic Design Pattern: Surrogate Fitness Functions

Certain problems have characteristics that present difficulties for metaheuristics: their objective function may be either prohibitively expensive, or they may only give a partial ordering over the solutions, lacking a suitable gradient to guide the search. In such cases, it may be more efficient to use a surrogate fitness function to replace or supplement the objective function. This paper provides a broad perspective on surrogate fitness functions, described in the form of a metaheuristic design pattern

Nano-Pervaporation Membrane with Heat Exchanger Generates Medical-Grade Water

A nanoporous membrane is used for the pervaporation process in which potable water is maintained, at atmospheric pressure, on the feed side of the membrane. The water enters the non-pervaporation (NPV) membrane device where it is separated into two streams -- retentate water and permeated water. The permeated pure water is removed by applying low vapor pressure on the permeate side to create water vapor before condensation. This permeated water vapor is subsequently condensed by coming in contact with the cool surface of a heat exchanger with heat being recovered through transfer to the feed water stream
