The subtraction method is a technique critical to several important acoustic measurements. It involves subtracting a reference measurement including only direct sound from one with direct sound and a reflection, to isolate the reflection. The process is very sensitive to environmental conditions, such as changes in temperature, air movement, and microphone positioning. These variations cause sm...

Contradictory results have been reported regarding the accuracy of various methods used to assess student learning in higher education. The current study examined student learning outcomes across a multi-section and multiinstructor psychology research course with both indirect and direct assessments in a sample of 67 undergraduate students. The indirect method measured student perceived knowled...

Although recent clinical studies using transcranial direct current stimulation (tDCS) for schizophrenia showed encouraging results, several tDCS montages were employed and their current flow pattern has not been investigated. We performed a systematic review to identify clinical tDCS studies in schizophrenia. We then applied computer head modeling analysis for prediction of current flow. Out of...

The characteristics of a series direct current (DC) arc-fault including both electrical and thermal parameters were investigated based on an arc-fault simulator to provide references for multi-parameter electrical fire detection method. Tests on arc fault behavior with three different initial circuit voltages, resistances and arc gaps were conducted, respectively. The influences of circuit cond...

Distinguishing transient blocks from frequently used blocks enables servicing references to transient blocks from a small highly-associative auxiliary cache structure. By inserting only frequently used blocks into the main cache structure, we can reduce the number of collision misses, thus achieving higher performance and allowing the use of direct mapped caches which offer lower power consumpt...

Monte Carlo models are used to describe the interaction between the incident pick-up ions and the Mars neutral atmosphere. The sputtered population inside the corona and escaping particles are described using a modi4ed 3D test particle model, whereas, the heating e6ect due to the incident 7ux is described using a 2D Direct Simulation Monte Carlo. These results show that the standard 1D models o...

Introduction The anatomy of the donkey and how it differs from that of the horse rarely receives mention in standard veterinary anatomy textbooks used in the western world. There is also limited material on this subject readily accessible in the current literature. As a result, the donkey is often presumed to be morphologically the same as the horse, and there are far more similarities between ...
