Abstract A healthy diet is essential to various health outcomes that are common among minority aging populations. To explore frequencies and correlates of food consumption among U.S. Chinese older adults, this study used data from the Population-based Study of Chinese Elderly (PINE) collected in Chicago during 2015-2017 (N=3053). Food consumption frequencies of five food groups (vegetables, fruits, grains, protein foods, and dairy) were assessed by a validated 48-item food frequency questionnaire. All responses of consumption frequency were transformed to “times per day” and weighted by report

This study aimed to determine consumers’ liquid choices, their consumption frequencies and habits. The study was conducted on 332 individuals aged between 16 and 30 (mean age: 20.7 ± 3.1 years). The most important factors that affect consumers’ liquid choices are tastiness (74.7%), easy accessibility (71.4%) and being a continuously consumed beverage (69.3%), respectively. Of the participants, 78.0% consumed liquids at meals, 66.3% of them started the day with a drink, 65.4% controlled alcohol content in energy drinks, 62.3% consumed water while eating, 50.0% consumed water in the recommended

Food-based recommendations (FBR) developed using linear programming generally use dietary intake and energy and nutrient requirement data. It is still unknown to what extent the availability and selection of these data affect the developed FBR and identified problem nutrients. We used 24 h dietary recalls of 62 Kenyan children (4–6 years of age) to analyse the sensitivity of the FBR and problem nutrients to (1) dietary intake data, (2) selection criteria applied to these data and (3) energy and nutrient requirement data, using linear programming (Optifood©), by comparing a reference scenario w

Breathing, heart and gait frequencies, tidal volume, cardiac output, and rates of oxygen consumption were measured in tammar wallabies (Macropus eugenii Desmarest) hopping on a treadmill. At speeds greater than 1.6 ms-1 the rate of metabolic power consumption was independent of hopping speeds. Blood lactate levels within the speed range where VO2 was independent of speed showed a mean increase of 4.8 mmol l-1. During bipedal hopping, the frequencies of breathing and limb movement are phase-locked in the ratio of 1:1. Inspiration begins as the animal leaves the ground and may be a passive proce

AbstractSilicon neurons represent different levels of biological details and accuracies as a trade-off between complexity and power consumption. With respect to this trade-off and high similarity to neuron behaviour models, relaxation-type oscillator circuits often yield a good compromise to emulate neurons. In this chapter, two exemplified relaxation-type silicon neurons are presented that emulate neural behaviour with energy consumption under the scale of nJ/spike. The first proposed fully CMOS relaxation SiN is based on mathematical Izhikevich model and can mimic a broad range of physiologi

The ESP32 is a popular microcontroller for IoT use cases. For many IoT applications (e.g., environmental sensors or wearables), a continuous power supply is either not possible or too cumbersome, requiring battery operation. However, the ESP32 has a relatively high power consumption. This chapter focuses on battery life optimization methods for this family of microcontrollers. For scenarios where data logging is relevant, methods for increasing communication speed in relation to power consumption are examined in detail.

Abstract Abstract. This paper develops tests for roots in linear time series which have a modulus of one but which correspond to seasonal frequencies. Critical values for the tests are generated by Monte Carlo methods or are shown to be available from Dickey-Fuller or Dickey-Hasza-Fuller critical values. Representations for multivariate processes with combinations of seasonal and zero-frequency unit roots are developed leading to a variety of autoregressive and error-correction representations. The techniques are used to examine cointegration at different frequencies between consumption and in

This chapter presents a wireless interface for intra-vehicle communications (data acquisition from sensors, control, and multimedia) at 5.7 GHz. As part of the wireless interface, a RF transceiver was fabricated in the UMC 0.18 µm RF CMOS process and when activated, it presents a total power consumption of 23 mW with the voltage-supply of 1.5 V. This allows the use of only a coin-sized battery for supplying the interface. The carrier frequency can be digitally selectable and take one of 16 possible frequencies in the range 5.42-5.83 GHz, adjusted in steps of 27.12 MHz. These multiple carriers

LNA is an electronic amplifier that is required in receiver systems to increase the amplitude of the very low level signals from the antenna without adding too much noise. Software Advance Design System (ADS) was used to simulate the circuit and design the layout. LNA was designed using cascode topology with feedback techniques which produces better matching and unconditionally stable over the entire desired frequencies. For the 2.4 GHz operation, the amplifier achieves gain of 14.949 dB, noise figure of 1.951 dB and input reflection coefficient of -10.419 dB. With operating voltage supply at

Traffic comprises a large and persistently growing share of resource consumption and environmental stress in modern economies. Even on our way towards an Information and Knowledge Society, the demand for physical transport has not let up. Although the total physical mass transported is no longer increasing in modern economies, the distances and exchange frequencies still are, both in freight and in passenger traffic. That is making traffic with its effects on the environment into one of the most difficult problems that has to be solved if we want to attain sustainable development.

It is important to understand the factors influencing power consumption in these devices if they are to be applied in cooling system designs.

An adaptive, model-free on-off controller is described for situations in which a desired step response is to be repeated many times, but there is incomplete information available about the system dynamics. The controller adapts a set of on-off switching transition times as a function of certain objective measurements defined by the designer. While the controller does not utilize any model of the system to perform this adaptation, the effects of the adaptation on known plants can be analyzed to find a range of systems for which the on-off switching times will result meeting desired objectives.

This paper proposes a technology to reduce vehicle surge during towing that utilizes motors and shifting to help ensure comfort in a parallel HEV pickup truck. Hybridization is one way to reduce fuel consumption and help realize carbon neutrality. Parallel HEVs have advantages in the towing, hauling, and high-load operations often carried out by pickup trucks, compared to other HEV systems. Since the engine, motor, torque converter, and transmission are connected in series in a parallel HEV, vehicle surge may occur when the lockup clutch is engaged to enhance fuel efficiency, similar to conven
