Lumped Construction Sequence for Column Shortening Analysis in High Rise Building with Outrigger System
Abstract: The exact value of column shortening is not a straightforward task. Various parameters are affected on column shortening results like rate of construction sequence and reinforcement ratio. The building should stand with high stiffness and must be able to resist lateral deformation without having discomfort to the user. The excessive drift is controlled by using outrigger system. In high rise buildings, the construction sequence analysis and conventional sequence analysis are …

Analogous Electrical Modelling of Squeeze Film Damping in MEMS Accelerometers
Abstract: Most of the MEMS (microelectromechanical systems) structures employ parallel plates or beams. A very thin film of air or some other gas in between their suspended structure and fixed substrate is trapped in between these plates. This results in squeeze film damping. Though, FEM (Finite element method) analysis is the most widely used method for studying the effects of the phenomenon, it becomes quite cumbersome and time consuming while analyzing …

A Ventilated Dual-Function Photonic–Phononic Metasurface for Simultaneous Passive Radiative Cooling and Low-Frequency Noise Mitigation in Building Envelopes: Conceptual Design and Computational Feasibility Analysis
Abstract: Acoustic metamaterials for sound insulation and photonic/radiative-cooling metamaterials for passive thermal management have each matured separately for building-envelope retrofit, but existing studies address ventilation, acoustic damping and radiative thermal control in isolation, and no reported unit-cell architecture co-designs all three within a single shared structure. This gap persists because materials that are acoustic absorptive are generally dense and structurally opaque, whereas materials that are highly solar-reflective are conventionally applied to …

Dynamic Modelling and State-Feedback Control of a Rotational Base Flexible Link Manipulator
Abstract: In this paper, dynamic modelling of single-link flexible robot manipulator is presented using lumped parameter method in a different approach. Model is simulated using MATLAB/ SIMULINK. State feedback controller is used to control the hub angle and tip deflection. Effectiveness of the controller is shown with different payload. State feedback using pole-placement; work satisfactorily with the change in the feedback gain matrix.

Development and Evaluation of Neural Network Model for Incident Detection on Urban Arterials using Simulated Database
Abstract: Incident detection in urban arterial situation is more difficult than the similar job in freeway situation because of the presence of traffic signals and other intersections with associated recurrent queue. Most of the earlier automatic incident detection algorithms address mainly freeway situation. This study aims at development, calibration, validation and testing of an ANN model for incident detection in Kuala Lumpur (KL) arterials using simulated incident database. Database for the …

A Model of Bidding in Rotating Saving Credit Associations
Abstract: The paper analyzes bidding behavior in discount bidding Roscas under the assumption of risk neutrality. Roscas are group based revolving financial schemes. In discount bidding Roscas, individuals bid for a lumpsum. We find that bids submitted by members in equilibrium are increasing in the returns or opportunities for investment. Further, members submit lower bids when credit is available outside Rosca at expensive rates. A bidding Rosca is efficient as an …

Drum-Boiler Dynamics and its Water Level Control
Abstract: Boilers used for continuous steam generation on large scale. Controlling aspect in boiler process is highly difficult as the system is complex and exhibit nonlinearity, the dynamics of boiler varies with load and multivariable dependent. The main cause of instability in boiler operation is due to the integration effect in it. In addition to that, boilers are normally used where there is sudden load variation without prior knowledge. In this …

The Transient Performance of Power Line Towers
Abstract: This paper presents a refined approach to the transient analysis of power line towers. Each section of the tower’s steel structure is accurately modeled as a non-uniform transmission line. Among other features, an efficient representation of the towers’ cross-arms as open-ended non-uniform lines and their subsequent approximation by lumped capacitors will be explored. Furthermore, the error introduced by neglecting the presence of the cross-arms, as well as the effect of …

Travel Demand Management for Sustainable Urban Transport in Kuala Lumpur: Operation and Energy Consumption Issues
Abstract: A number of South-East Asian cities are experiencing rapid growth in car ownership and overall transportation demand in the context of relatively low fuel and road tax along with land use patterns that encourage private automobile trips. To address these challenges, sustainable transport initiatives, which often include travel demand management (TDM), are increasingly being promoted at the city level. This paper examines the effectiveness of TDM on reducing road traffic …

Comparative Cooling Analysis of EV Battery Packs using MATLAB Simscape
Abstract: Since electric vehicles (EVs) transition to high- voltage systems to enable quicker charging and enhanced delivery of power, the high heat emitted during rapid discharge is a significant challenge. This paper presents a direct comparative study of passive air cooling and active liquid cooling of a lithium-ion battery pack. Due to the high cost of constructing the physical prototypes, we created a computationally efficient and hierarchical virtual prototype in MATLAB …
