Facial Expression Classification

Drivers’ road rage is among the main causes of road accidents. Each year, it contributes to more deaths and injuries globally. In this context, it is important to implement systems that can supervise drivers by monitoring their level of concentration during the entire driving process. In this paper, a module for Advanced Driver Assistance System is used to minimise the accidents caused by road rage, alerting the driver when a predetermined level of rage is reached, thus increasing the transportation safety. To create a system that is independent of both the orientation of the driver’s face and the lighting conditions of the cabin, the proposed algorithmic pipeline integrates face detection and facial expression classification algorithms capable of handling such non-ideal situations. Moreover, road rage of the driver is estimated through a decision-making strategy based on the temporal consistency of facial expressions classified as “anger” and “disgust”. Several experiments were executed to assess the performance on both a real context and three standard benchmark datasets, two of which containing non-frontal-view facial expression and one which includes facial expression recorded from participants during driving. Results obtained show that the proposed module is competent for road rage estimation through facial expression recognition on the condition of multi-pose and changing in lighting conditions, with the recognition rates that achieve state-of-art results on the selected datasets.

The Distributed Electro-hydraulic Braking system (DEHB) is a wet type brake-by-wire system. As a safety critical automotive electrical and/or electronic (E/E) system, DEHB shall be designed under the guideline of ISO 26262 in order to avoid unreasonable risk due to the malfunctions in the item. This paper explores how the Automotive Safety Integrity Level (ASIL) decomposition in the concept phase is influenced by the system architectures of DEHB. Based on a typical hazardous event, analysis on DEHB with the same system architecture as the Electro-mechanical Braking system (EMB) is carried out, which is taken as the basis for comparison. Two types of DEHB with different system architectures are then analyzed. Results show that the adoption of hydraulic backup enables ASIL decomposition in the pedal unit. The adoption of both hydraulic backup and normally open balance valves offers the opportunity to perform ASIL decomposition in the brake actuator system of DEHB.

Subject area Marketing management – services marketing specialization. Student level/applicability MBA/PGDM senior students studying services marketing as a specialization course. Case overview US Technology Private Ltd (UST) is a major software services company in India. It was started in 1999 with a few employees at an offshore development centre in Trivandrum. Now in 2010, renamed UST Global, the company has over 7,000 employees worldwide. Phenomenal success of such a software company, in the left-oriented party dominated state of Kerala, has invited the attention of many people in the industry. The company earned valuable foreign exchange through software exports for the country and the state over the last ten years. The company has created innovative service differentiators, to impress on its clients, on the advantage of doing business with the company. The cementing customer satisfaction and derived customer delight that the company has created in their clients, has secured stable customer relationship management and customer loyalty. This reinforces the trust they have shown in the services management philosophy adopted by the company. The company's unique hybrid delivery model has worked well with its clients. Its unique selling proposition of “few clients and more focus” has resulted in delight of its customers, as they see it as a value addition for their money's worth. The leadership team attributes the success of the company to its fundamental core values and twin strategy of customer centricity and employee focus. Expected learning outcomes These are: customer perception of service; purpose of customer relationship management; service differentiators; and employees' role in delivering successful software service solutions to the customer, etc. Supplementary materials Teaching notes.
