Re-arranging the urban: forms, rhythms, politics by Abdullah, Adam, Cardoso, Ricardo, Dasgupta, Shreyashi, Pati, Sushmita, Plueckhahn, Rebekah, Shafique, Tanzil, Simone, AbdouMaliq, Teo, Shaun S. K., Ye, Junjia, Zhao, Yimin

“…Involving workarounds, collaborations, exchanges, and agreements that exceed the familiar protocols of interaction among households, local authorities, markets, civil institutions, brokers, and service providers, arrangements entail the enactment of caring, provisioning, regulating, mapping, and steering as the purview of more provisional, incessantly mutating forms that fold in bits and pieces of discernible institutions. In this heuristic intervention we seek to further the ‘urbanisation’ of urban geography itself, in the sense of complexifying both the terrain and the methodological practices brought to bear. …”

Compressive sensing based video object compression schemes for surveillance systems by Narayanan, Sathiya, Makur, Anamitra

“…If the foreground moving objects are segmented from the background they can be coded independently requiring far fewer bits compared to frame-based coding. Huang et al proposed a Compressive Sensing (CS) based Video Object Error Coding (CS-VOEC) where the objects are segmented and coded via motion estimation and compensation. …”

A CMOS equivalent-time sampling digitizer for a direct-millimeter-wave UWB pulse doppler radar receiver implementation by Jaya, Gibran Limi

“…The prototype is measured to be capable of digitizing signals with frequencies of up to 64 GHz while maintaining an effective number of bits (ENOB) of >3.2 bits. This performance is achieved with a power consumption of <20 mW and a modest figure of merit without needing the digitizer to be fabricated in a much more advanced CMOS technology node. …”

Titanium in Cast Cu-Sn Alloys—A Review by Karthik Manu, Jan Jezierski, Madikkamadom Radhakrishnan Sai Ganesh, Karthik Venkitaraman Shankar, Sudarsanan Aswath Narayanan

“…It has also been reported that bronze alloys are especially used as an anti-wear and friction-reducing material to make high performance bearings for roller cone cock bits and warships for defence purposes. In these applications, properties like tensile strength, yield strength, fatigue strength, elongation, hardness, impact strength, wear resistance, and corrosion resistance are very important; however, these bronze alloys possess only moderate hardness, which results in low wear resistance, thereby limiting the application of these alloys in the automobile industry. …”

A Fast and Low Distortion Image Steganography Framework Based on Nature-Inspired Optimizers by Magdy M. Fadel, Wael Said, Esam A. A. Hagras, Reham Arnous

“…Several algorithms have been developed to determine the optimal embedding capacity of every pixel to enhance steganography techniques. Concealing secret bits is not the only challenging aspect of this operation; improving the embedding capacity of secret data is also important, as is maintaining an acceptable visual quality after concealment. …”

Performance Improvement of Polar Codes via UEP Product Coding by Yiting Liang, Huihui Wu, Kui Cai, Lin Wang

“…In order to address this problem, this paper provides an analytical formulation by maximizing the number of correctly decoded information bits.

Technological analysis and experimental reproduction of the techniques of perforation of quartz beads from the Ceramic period in the Antilles by Raymond, Madeleine, Fouéré, Pierrick, Ledevin, Ronan, Lefrais, Yannick, Queffelec, Alain

“…This hard material (7 on the Mohs scale), represented as rock crystal and amethyst in the collections, is indeed very difficult to perforate without the use of metal drills or harder minerals used as drill-bits or abrasives such as diamond or emery. In this work we demonstrate that it is possible to produce these perforations with cactus thorns and crushed quartz as abrasive powder. …”

New ECG Compression Method for Portable ECG Monitoring System Merged with Binary Convolutional Auto-Encoder and Residual Error Compensation by Jiguang Shi, Fei Wang, Moran Qin, Aiyun Chen, Wenhan Liu, Jin He, Hao Wang, Sheng Chang, Qijun Huang

“…BCAE directly compresses the ECG signal into binary codes rather than floating-point numbers, whereas binary codes take up fewer bits than floating-point numbers. Compared with the traditional floating-point number compression method, the hidden nodes of the BCAE network can be artificially increased without reducing the compression ratio, and as many hidden nodes as possible can ensure the quality of the reconstructed signal. …”
