Modeling Florida Fresh Tomato Supply Response: Composite Switching Regressions with Variable Weather-Determined Lags

A supply-response model for Florida fresh tomatoes is specified to analyze the impacts of the U.S. Department of Commerce's suspension agreement which governs imports of fresh tomatoes from Mexico. The particular focus is on the impact of the "reference" price which causes Mexican imports in a given week to cease if import prices in the prior week fall to the reference price. Using weekly weather data, a growing degree day (GDD) variable is constructed which predicts week of first harvest and duration of harvest. The GDD variable is used to construct the appropriate, variable lag length for weekly acres planted in four Florida production regions. A composite switching-regime model is estimated in which the regime prior to the suspension agreement occurs at a known time. The other two regimes occur when Nogales f.o.b. price are "near" or not near the reference price. Preliminary results suggest weekly Florida shipments of fresh tomatoes are more own-price elastic when Nogales f.o.b. prices near the reference price.International Relations/Trade,

IoT based Ambulance Prototype for Innovative Traffic Congestion Control System

Traffic congestion is a major problem in cities of developing Countries like India. Growth in urbanpopulation and the middle-class segment contribute significantly to the rising number of vehicles inthe cities. Congestion on roads eventually results in slow moving traffic, which increases the time oftravel, thus stands-out as one of the major issues in metropolitan cities. This paper presents anintelligent traffic control system to pass emergency vehicles smoothly. Each individual vehicle isequipped with special radio frequency device. We use radio frequency (Rf)transmitter (Tx) andreceiver (Rx) modules at ambulance and traffic signal respectively. It monitors vehicles that passes ona path during a specified duration. It also determines the network congestion, and hence the greenlight duration for that path. If the ambulance passes through the path it switches on the green lightuntil it passes the signal area

Combustion knock detection and control through statistical characterization of knock levels

A method of statistically characterizing combustion knock events includes receiving signals from a sensing device such as an accelerometer, estimating at least one parameter of a probability distribution function based on the received signals, and calculating a value indicative of an r/h percentile based on the parameter to predict upcoming combustion knock events.https://digitalcommons.mtu.edu/patents/1030/thumbnail.jp

Die Life Prediction of Connecting Rod SIFL-175

This work mainly focuses on the life prediction of hot forging dies of connecting rod SIFL-175. This prediction helps the forging industry in estimating the quantity of products forged before reworking or resinking and thereby can supply the forgings to the customer at reasonable lower price and this will also escalating the demand from the customer. The prediction of die life is vital to satisfy demands for lower cost and shorter production preparation times. The prediction helps the company to make an accurate production planning process and can take necessary steps and actions to utilize the maximum quantity of products before die failures

Optimized differential TCDA (D-TCDA) with novel differential feed structure

Modern phased arrays require large instantaneous bandwidths, wide fields of view, and low profiles to conduct multiple functions. Many of these phased arrays rely on emerging high speed ADCs and advanced balanced transceivers. The benefits of balanced front-ends include improved linearity, dynamic range, isolation, and noise resilience. The application of a differential phased array in such a system removes extraneous losses caused by baluns, though the issue of feed-borne E-plane scan resonances must be considered. We address the E-plane scan resonance issue through an improved Balanced Wideband Impedance Transformer (BWIT) feed for the ultra-wideband (UWB) Tightly Coupled Dipole Array (TCDA). This BWIT feed has already demonstrated mitigated common-modes over a 3:1 bandwidth ratio while scanning to low angles. Here, our differential TCDA (D-TCDA) is developed for the L-C band (viz. 1.0 GHz to 6.1 GHz) with emphasis on resonance-free wide-angle scanning. Rigorous EM model and circuit analysis is included to verify the BWIT performance. Under a VSWR \u3c 3 definition, the improved array achieves a 6:1 impedance bandwidth ratio (BWR) with resonance-free scanning in all planes. An exception is the H-plane scanning at 60◦ where the VSWR \u3c 4. Array simulations are verified with measurements for an 8×8 single-polarized prototype

GREEN TEA CATECHIN LOADED NANODELIVERY SYSTEMS FOR THE TREATMENT OF PANDEMIC DISEASES

Tea (Camellia sinensis, Family: Theaceae) is one of the extremely consumed beverages around the world, behind to water. The brew tea is the merely food product contains abundant quantity of the catechins. Green tea is the least processed and thus contains rich antioxidant, polyphenols, especially catechin called epigallocatechin-3-gallate (EGCG), which is whispered to be responsible for a wide range of the health benefits. The key to the amazing health benefits that are derived from green tea is that the leaves are steamed which preserves the EGCG compound from being oxidized. However, the other varieties of teas are under go fermentation process, which breaks down the potential EGCG and destroy from its healing properties. In reality, green tea has very extensive history dating back thousands and thousands of years ago. However, the pharmacological efficacy and stability of green tea catchiness are primarily depended on the formulation and way to drink to alleviate the deadly diseases with scientific evidence. Nanotechnology is a vibrantly emerging field especially in the pharmaceutical industry to explore a lot of application. The promising nano-delivery system used to enhance the therapeutic efficacy with a minimal dose, minimize the dose-related toxicity, target delivery, site-specific delivery, and controlled/sustain the delivery application. In recent decades, the application of nanotechnology has been utilized for phytopharmaceutical industry including green tea catechins to maximize the health benefits. In this review, we tried our level best retrieve the value of information on nanodelivery application of green tea catchiness for various devastating diseases
