DEVELOPING AND VALIDATING ENERGY MODELS FOR INDIRECT AND DIRECT EVAPORATIVE COOLING USED IN DATACENTERS
(2016-08-23)
In the present day to day life, Internet of things is everything, i.e., we need internet and telecommunication for almost every task of our life and these require data from data centers. These data centers provide various ...
Understanding the Alchemilla leaf and its hydrophobicity
(2016-08-26)
The Alchemilla leaf has been well known and studied frequently for its hydrophobic ability. However, much difficulty has been met in replicating its microstructure for hydrophobic applications. Also, not much experimental ...
FITTING B-SPLINES CURVES TO COARSE DATA CLOUD USING MODIFIED SQUARED DISTANCE MINIMIZATION METHOD
(2016-08-22)
Additive manufacturing has made us realize that we can fabricate complex shapes that were difficult to manufacture with subtractive processes. Topology optimizations results have complex shapes and have rough surfaces which ...
Thermal Energy Storage for Expanded Use of Data Center Indirect/Direct Evaporative Cooling
(2016-08-10)
Computer cooling system design evolved over time with goals of increasing efficiency and decreasing cost. Early computers were essentially hand-built and very expensive. Reliable operation required aggressive cooling to ...
Integration of a Portfolio-based Approach to Evaluate Aerospace R&D Problem Formulation Into a Parametric Synthesis Tool
(2016-09-15)
The focus of this study is to improve R&D effectiveness towards aerospace and defense planning in the early stages of the product development lifecycle. Emphasis is on: correct formulation of a decision problem, with special ...
PERFORMANCE ANALYSIS, DYNAMIC SIMULATION AND CONTROL OF MASS-ACTUATED AIRPLANE
(2016-08-12)
The control of space, aerial and underwater vehicles requires moment generation mechanisms to change their orientation. In addition to or in place of conventional moment generation actuators, internally moving-mass actuation ...
EMBEDDING ANTENNA SHEAR/PRESSURE SENSORS IN PROSTHETIC LINER MATERIAL
(2016-08-26)
Published surveys indicated that 40-60% of prosthesis users experience discomfort and skin problems. These studies highlighted the needs for enhanced prosthetic performance and fit. It is extremely difficult to address ...
RELIABILITY CHALLENGES IN AIRSIDE ECONOMIZATION AND OIL IMMERSION COOLING
(2016-05-16)
The Datacom facility which comprises rooms or closets used for communication, computers/servers or electronic equipment requires cooling unit which consumes 31% (23% HVAC cooling + 8% HVAC fans) of overall energy. The ...
HUMAN ROBOT INTERACTION USING KNOWLEDGE BASE APPROACH
(2016-05-10)
This research investigated Human Robot Interaction modalities. The performance of a robotic prosthetic hand (RPH) was used as a test bed robot. A user wearable glove was fitted with sensors to provide tele-control of the ...
Analysis of an Artificial Tailplane Icing Flight Test of a High-Wing, Twin-Engine Aircraft
(2016-05-13)
The US Air Force Flight Test Center (AFFTC) conducted a civilian, Federal Aviation Administration (FAA) sponsored, evaluation of tailplane icing of a twin-turboprop business transport at Edwards Air Force Base. The flight ...
