Early detection of dementia is becoming increasingly important as it plays a crucial role in handling the patients and offering better treatment. Many of the recent studies concluded a tight relationship between dementia and gait disorders. For this purpose, identification of gait abnormalities is key factor. Novel technologies provide many options such as wearable and non-wearable approaches for analysis of gait. As the occurrence of dementia is more prominent in elderly people, wearable technology is considered out of scope for this work. The gait data of several elderly people over 80 years is acquired over certain intervals during the scope of the project. The elderly people are classified into three study groups namely cognitively healthy individuals (CHI), subjectively cognitively impaired persons (SCI) and possible mildly cognitively impaired persons due to inconclusive test results (pMCI) based on their cognitive status. The gait data is acquired using Kinect sensor. The acquired data consists of both RGB image sequences and depth data of the test persons. 3D human pose estimation is performed on this gait data and gait analysis is done. The transformations in the gait cycles are observed and the health condition of the individual is analyzed. From the analysis, the patterns in the gait abnormalities are correlated with the above-mentioned classification and are used in the detection of dementia in advance. The obtained results look promising and further analysis of gait parameters is under progress.

The implementation of accurate solutions to synchronize the transceiver's clocks in real-time operations plays a major role in the current development of communication systems. Considering the orthogonal frequency division multiplexing (OFDM)-based systems, adopted for the deployment of fifth-generation mobile networks (5G), industrial networks, and the wireless local area network (WLAN) standard, several reported solutions focus on field-programmable gate array (FPGA) designs for the clock synchronization in real-time operations. However, reported solutions describe with minor details the impact of the introduced quantization noise error (QNE) based on the implemented bit-width. Their studies provide insights to implement digital solutions of reduced complexity. The current article provides theoretical expressions to characterize accuracy and precision while synchronizing the transmitter's clock. The presented analysis is intended to support designers to evaluate the clock synchronization design considering the bit-width for implementing the given system.

Due to the current changes in the age pyramid and the need for the elderly to be mobile, more and more people want to use their car even up to high age. Age-specific changes should not impair the driving performance of the drivers. For this purpose, new techniques to improve road safety are required. Aim of the ViFa 65+ project is to develop and evaluate a visual driver assistance system to compensate age-related changes. The specific needs of elderly drivers have been examined and lead to a realization of a visual assistance system with a full windshield image projection.

Recently, in acoustic and audio engineering where wideband signals are handled, it has become required to realize a large-scale adaptive filter by small computational complexity. This paper proposes an efficient adaptive filter, based on the time-frequency characteristics of the impulse response of the unknown system. First, the filter structure is shown which can extract the time-frequency characteristics of the impulse response of the unknown system. Then a nonuniform resolution filter is proposed which can represent the impulse response in the time-frequency domain with a nonuniform resolution by allocating a small number of tap coefficients. An adaptive algorithm based on the proposed filter structure is derived. Finally, it is shown by a simulation that the computational complexity can be reduced by the proposed method when the unknown system has a nonuniform structure in the time-frequency domain.
