This paper studies the lateral stability regulation of intelligent electric vehicle (EV) based on model predictive control (MPC) algorithm.

Firstly, the bicycle model is adopted in the system modelling process. To improve the accuracy, the lateral stiffness of front and rear tire is estimated using the real-time yaw rate acceleration and lateral acceleration of the vehicle based on the vehicle dynamics. Then the constraint of input and output in the model predictive controller is designed. Soft constraints on the lateral speed of the vehicle are designed to guarantee the solved persistent feasibility and enforce the vehicle’s sideslip angle within a safety range.

The simulation results show that the proposed lateral stability controller based on the MPC algorithm can improve the handling and stability performance of the vehicle under complex working conditions.

The MPC schema and the objective function are established. The integrated active front steering/direct yaw moments control strategy is simultaneously adopted in the model. The vehicle’s sideslip angle is chosen as the constraint and is controlled in stable range. The online estimation of tire stiffness is performed. The vehicle’s lateral acceleration and the yaw rate acceleration are modelled into the two-degree-of-freedom equation to solve the tire cornering stiffness in real time. This can ensure the accuracy of model.

The informal segment compared to the formal segment is developing rapidly in urban areas of many developing Muslim countries. However, matter of fact, the contribution factor of the food cart business to the economic outline of the country has been vastly overlooked or neglected. The authority, policymakers, social organisations, vendors and the customers together need to play a contributing role based on intervention tactics regarding the major focus areas related to the development of this business segment. As a result, this study aims to explore concerns or issues that are hampering future business prospects considering the philosophy of halalan tayyiba.

The study has organised 16 semi-structured interview procedures with relevant food cart vendors of Chittagong, Bangladesh. The study selected participants (food cart vendors) from lower- to medium-income areas occupying at least one high school, one college in relation to several commercial premises (ex-mini shopping malls, offices and small factories) considering 6 out of 41 wards of Chittagong city corporation. All meetings with reflected participants were audiotaped and transcribed verbatim and transcripts were loaded into NVivo for coding and analysis procedure.

This investigation revealed that issues with food security, weather, lack of proper legislation, lack of awareness related with halalan tayyiba and erratic policies are the major challenges for the development of the food cart business in Chittagong. This study also advances how street food security well-being and hygiene practices are a piece of the halal idea and should in this way be adjusted by the halal food segment to accomplish halalan tayyiba affirmation. The outcomes also indicate an agenda for future research in this area.

More reflections from the different stakeholders do have both pertinence and potential for incorporation in suggestions.

The detected findings may help both authority and other concerned entities to identify the critical dynamics to initiate appropriate strategic activities towards local economic growth considering halalan tayyiba outlines.

It will ensure social well-being and food security.

This explorative research is one of few studies in the Bangladesh context, which is investigating halalan tayyiba-oriented business development outline for micro entrepreneurs.

The authors combine options logic with transaction cost economics to explain why firms maintain, divest or buy out their international joint ventures (IJVs). It is suggested that a decline in environmental risk and higher partner-related risk makes a firm more likely to acquire an IJV but less likely to divest an IJV. The study also investigates how IJV age moderates the effects of a decline in environmental risk and higher partner-related risk.

The study employs competing risks analyses to examine the drivers of different termination outcomes using a dataset consisting of 459 IJVs in the People's Republic of China, of which 110 were either acquired or divested by their foreign parent.

The study finds that changes in environmental risk and partner-related risk affect how firms terminate their IJVs in the People's Republic of China. Specifically, the authors find that the effect of exogenous and endogenous risk are more pronounced for the acquisition of IJVs than for the divestment of IJVs.

The study contributes to international marketing research by complementing options logic with transaction cost economics to provide a theoretical explanation of the different ways in which IJVs in the People's Republic of China are terminated.

IJVs continue to be an important yet often unstable method to serve international markets. Our findings increase managers' awareness of the effect that two important sources of risk may have on the termination of IJVs in the People's Republic of China.

The study provides novel insights into the effect that changes in exogenous and endogenous risk have on a firm's choice of termination mode drawing on novel data on the different ways in which foreign firms have terminated their IJVs in the Peoples' Republic of China.

Mitigating the energy trilemma (ET) is of great importance for dealing with climate change and realizing carbon neutrality. To this end, effectively assessing the level of the ET is essential. The purpose of this study is to evaluate the current situation and the spatio-temporal changes of the ET in the whole of China.

Moreover, based on provincial-level data in China for the period 2002–2017, and by using the dynamic estimation model, we aim to determine the specific marginal impacts of smart transportation (ST) on the ET, and the possible channels through which ST works on the ET.

We thus present the following findings: (1) The performance of both ET and its three pillars is gradually improving in China. Moreover, the situation tends to vary dramatically among various regions and provinces, and the gap between the best performers and the worst is large. (2) ST plays a significant role in inhibiting the ET, a finding that remains robust after a series of tests. And (3) the ET eradication effect of ST is caused mainly by improved innovation, advanced technical efficiency, and the increasing energy scale.

Accordingly, we put forward some policy recommendations to help tackle ET and accelerate ST in China.
