The datasets were determined from measurements with 13 subjects in a surrounding spherical microphone array with 32 microphones and then upsampled to a higher spatial resolution. The results show that hand postures strongly impact voice directivity and affect the directivity index by up to 6 dB, which is more than variances

This work represents a microstrip patch array antenna which is designed and analyzed for the application of circular polarization in X band frequency range. The proposed antenna array has a very simple microstrip line feeding mechanism and each patch is energized orthogonally to acquire circular polarization without the need for any phase shifters. The array antenna has a slot line in the ground to electrically couple the signals from the microstrip feed line to feed each patch. The outcome demonstrates that the antenna is capable of radiating both left-hand circular polarization (LHCP) and ri

Abstract:

Detection of vibration transmitted through an object grasped in the hand. A tool or probe often functions as an extension of the hand, transmitting vibrations to the hand to produce a percept of the object contacting the tool or probe. This paper reports the psychophysical results of a combined psychophysical and neurophysiological study of the perception of vibration transmitted through a cylinder grasped in the hand. In the first part of the psychophysical study, 19 subjects grasped a cylinder, 32 mm diam, with an embedded motor that caused vibration parallel to the axis of the cylinder. The

Introduction. In industrial environments, at the workplaces of hand tool operators, it is not always possible to completely eliminate increased levels of vibration exposure. The power and speed characteristics of modern hand-held machines are constantly increasing. The impact of local vibration on a person has a negative effect on his body. When working with hand tools, personal protective equipment is used. The purpose of personal hand protection against vibration is to reduce the vibration impact on a person. Materials and methods.

Abstract:

Clinical translation of photoacoustic (PA) imaging can be facilitated by integration with commercial ultrasound (US) scanners to enable dual-modality imaging. An array-based US scanner was modified for hand-held PA imaging. The performance was benchmarked in terms of signal-to-noise ratio (SNR), axial spatial resolution and sensitivity. PA images of a tube, filled with methylene blue (MB; approx. 30 mM) and placed at various depths in chicken tissue, were acquired. A 5 cm penetration depth was achieved with an 18.6 dB SNR using a laser fluence of 3 mJ cm −2 , only one-seventh of the safety lim

SAP SuccessFactors Learning, originally designed on Oracle’s row-based RDBMS, embedded extensive business logic within PL/SQL procedures, functions, and triggers. The application’s architecture was tightly coupled with Oracle SQL syntax and transactional operations, making direct migration to SAP HANA, a columnar, in-memory database, complex and performance-intensive.

SAP SuccessFactors Learning, a core component of the HCM suite, faces significant challengeswith its current HTTP session persistence model, which relies on HANA DB. This approachgenerates approximately 2.4 million daily SQL queries, leading to high CPU and I/O overhead,increased latency, and scalability limitations. Furthermore, during node failures, sessioncontinuity can be disrupted, impacting user experience and requiring costly database operations torecover.To address these challenges, this paper proposes transitioning session persistence from HANA DBto Redis, an in-memory data store know

Monolithic three-dimensional (3D) integration allows ultra-thin silicon tier stacking in a single package. The high-density stacking is acquiring interest and is becoming more popular for smaller footprint areas, shorter wirelength, higher performance, and lower power consumption than the conventional planar fabrication technologies. The physical design of monolithic 3D (M3D) integrated circuits (ICs) requires several design steps such as 3D placement, 3D clock-tree synthesis, 3D routing, and 3D optimization. Among these, 3D routing is significantly time-consuming due to countless routing bloc

To reduce mutual coupling between the MIMO antenna element a separate ground plane is designed and the two elements are positioned on the edges of the 2-element MIMO antenna system. A novel idea defined in order to reduce mutual coupling between the closely spaced micro-strip patch elements is adding finger shapes at the edge of each patch antenna to design a new crack finger micro-strip the fingers generate

ABSTRACTThe proposed article offered a closely packed circularly polarized MIMO antenna system for a 5G NR n48/n78 communication system. The design consists of an E‐shaped antenna with modified arms along with shorting pins, and the edge‐to‐edge distance between the radiator is 0.2 mm. The proposed design offers isolation from 15 dB(minimum) to 47.35 dB(maximum) in the range of 3.3 to 3.9 GHz with a peak gain of 4.2 dBi. The uniqueness of this design here is the surface current cancellation technique within the design space of this E‐shaped antenna, which decouples the radiators with high comp
