Investigation of chatter stability in boring tool and tool wear prediction using neural network

Abstract: Chatter vibrations were induced during boring process due to cantilever shape of boring bars. These vibrations further leads to an increase in temperature of the boring tool which increases the tool wear. This present investigation is focused on selection of suitable damping material for the boring tool in various positions in order to reduce tool wear. Various damping materials such as copper, cast iron, brass, phosphor bronze, gun metal, steel and aluminium are considered for analysis. A conventional lathe which is attached with a temperature measurement setup was used to conduct experiments for various levels of speed, depth of cut, damping materials and its position from the cutting edge to measure tool wear and temperature. Tool wear and temperature were accurately predicted using artificial neural network model and it was compared with the experimental values.

Effective Shaping of Cold-Formed Thin-Walled Built-up Beams in Pure Bending

Abstract: Cold-formed thin-walled beams with an open cross section are widely used in different branches of industry. They tend to buckle in a variety of modes, which can be described as local, distortional, lateral-torsional buckling and bending. In this paper, the investigation on built-up I-sections, formed by assembling the stiffened cold-formed channel sections, with or without edge stiffener is presented. Parametric studies are carried out for five different section geometries with 16 specimens, tested under two point loading, to identify factors affecting the flexural strength of stiffened cold-formed steel built-up sections. The section geometries are chosen such that all types of buckling modes are met with. Critical load obtained from experiments is compared with finite element analysis results. Finally, it discusses the suitability of the current design methods (American Iron and Steel Institute) and provides design recommendations for stiffened cold-formed built-up sections.

Smartphone Enabled Intelligent Surveillance System

Abstract: Surveillance plays a crucial role in day-to-day life. A typical surveillance system continuously monitors its vicinity and stores the surveillance data locally. This may end up in lots of memory and energy wastage. Moreover, the surveillance records are under security threat, when the surveillance system is seized or damaged by the intruders. In this paper, a new design for surveillance using smartphone along with the passive infrared (PIR) sensor and the microcontroller unit (MCU) is proposed. The PIR sensor is attached to the smartphone through the MCU to detect motion. The video is captured only when the motion is detected and the short message services alert is sent to the user straight away. To overcome the memory restrictions of smartphone and to ensure the safe storage of surveillance records, it is uploaded in cloud, and the link is sent to the user through email. The proposed intelligent surveillance system offers cost effective, storage effective, energy efficient, and secured solution as it uses the computation and communication capabilities of the smartphone and the storage capabilities of cloud.

Ultra performance liquid chromatography (uplc) : a chromatography technique

Abstract: UPLC can be regarded as a new direction for liquid chromatography. UPLC refers to Ultra Performance Liquid Chromatography.UPLC, improve in three areas: ‘‘speed, resolution, and sensitivity’’. In this system uses fine particles (less than 2.5µm) so decreases the lengh of column, saves time and reduces solvent consumption.
