The problem of controlling the rectilinear motion of an open container without exceeding a prescribed liquid level and other constraints is considered using a recently-developed constrained sliding mode control design methodology based on invariant cylinders. A conventional sliding mode regulator is designed first to address nominal performance in the sliding mode. Then an robustly-invariant cylinder is constructed and used to describe the set of safe initial conditions from which the closed-loop controller can be operated without constraint violation. Simulations of a typical transfer illustrate the usefulness of the method in an industrial setting. Experimental results corresponding to a high-speed transfer validate the theory.

PurposeThe purpose of this paper is to explore the interplay between human resource management (HRM) and emergent factors in constructing a strong HRM climate. Specifically, the paper aims to shed light on how employee perceptions of the HRM process and emergent factors together construct a strong HRM climate, i.e. employees' shared perceptions of HRM.Design/methodology/approachThe paper uses qualitative interview data (managers and employees) from two organisations operating in Finland. The data are analysed based on a systematic data analysis and gives an illustration of the interplay between high-performance work system and the emergent factors.FindingsThe findings illustrate the three types of interplay between HPWS and emergent factors – supplementation, substitution and suffocation – that construct employee experience.Originality/valueThe paper extends earlier discussions on the relationship between HRM and employee experience by empirically examining how the HRM process – together with emergent factors – constructs a strong HRM climate. The present study contributes to further theorising and increasing our understanding of the creation of employee experience.

To meet the high performance demands of embedded multimedia applications, embedded systems are integrating multiple processing units. However, they are mostly based on custom-logic design methodology. Designing parallel multicore systems using available standards intellectual properties yet maintaining high performance is also a challenging issue. Softcore processors and field programmable gate arrays (FPGAs) are a cheap and fast option to develop and test such systems. This paper describes a FPGA-based design methodology to implement a rapid prototype of parametric multicore systems. A study of the viability of making the SoC using the NIOS II soft-processor core from Altera is also presented. The NIOS II features a general-purpose RISC CPU architecture designed to address a wide range of applications. The performance of the implemented architecture is discussed, and also some parallel applications are used for testing speedup and efficiency of the system. Experimental results demonstrate the performance of the proposed multicore system, which achieves better speedup than the GPU (29.5% faster for the FIR filter and 23.6% faster for the matrix-matrix multiplication).

Purpose Defines clear steps for growth planning that support answers to the crucial question: How and where are you planning to scale up the business and what talent do you need to implement this? Design/methodology/approach As the “Business model value matrix” shows, having ‘happy customers’ is only one determinant of a business model’s success. The other essential block of diagnostic questions deals with the current state and prospects of the firm’s growth. Findings We found that companies that have found ways to keep their business models in a winner’s state can provide clear, evidence-based answers to questions about growth opportunities and risks, while their less successful peers have difficulty addressing the issues. Continuous collecting and analyzing of this information allows successful companies to embrace the strategy-as-learning model of development, built around active learning and proactive adjustment to evolving environment. Practical implications To develop a strategy for moving to and sustaining the Winner state, managers must clearly articulate and test a set of hypotheses about the mechanisms of their company’s growth. The first step on this path is related to obtaining a clear view on the factors that underpin the current financial performance. Originality/value High-performance cultures make sure that each manager has the clear answers to the questions of value, growth and digitization in order to learn, experiment and implement the company business model agenda. The unproductive cultures, on the other hand, are sustained by managerial teams that usually do not have the answers to these crucial questions, but are very good at political games.

Purpose One of the most important characteristics of high-performance organizations is that these organizations always aim at servicing their customers as best as possible. In practice, this means that the employees of these organizations have to behave toward customers in such a way that these customers are not only fully satisfied but also become loyal to the organization. The purpose of this paper is to look at the concrete behaviors that are needed to create this customer loyalty. Design/methodology/approach From a literature review the items that potentially are of influence on creating customer loyalty and customer intimacy were identified, based on a previous validated questionnaire while adding additional items. These items were subsequently validated in practice with a questionnaire distributed among people who are in daily life regular customers of organizations. Findings The research results show that there are eight behavioral factors of importance to create customer loyalty and customer intimacy: first, service quality delivered by employees; second, capability of employees to deliver high quality; third, empathy of employees toward customers’ wishes and needs; fourth, understanding of employees of customers’ needs; fifth, responsiveness of employees toward the needs of customers; sixth, courtesy of employees toward customers; seventh, service manner of employees; and finally, trust customers place in employees. Research limitations/implications The implication of this research is that, now that the behavioral factors are known, an organization can make sure its employees focus on displaying these behaviors toward customers consistently over time, in order to make sure customers will experience the organization as a high-performance organization and will feel loyalty toward the organization. Originality/value The research described in this paper adds to the literature in the sense that it encompasses previous research into once item list and specifically looks at behaviors that create excellent service and thereby customer loyalty and customer intimacy, both concepts that go beyond the much researched topic of customer satisfaction.

PurposeIn this article, we identify various foodservice-related attributes that are important for undergraduate students residing in hostels and avail service from specific foodservice providers. We also investigate the performance of attributes to determine areas where the foodservice providers should maintain a high performance or where improvement is required.Design/methodology/approachWe apply the Kano methodology to design the questionnaire for 24 different attributes. For each attribute, we construct three questions; namely, functional type, dysfunctional type, and performance of the hostel foodservice. We collect a total of 317 responses. We use multiple methods to determine the dominant category. Finally, combining the values of these methods, we study relative positions of the attributes in the importance–performance grid.FindingsBased on the Kano categorization, quality-related attributes are most important, followed by hygiene, comfort, availability, variety, and time, in the descending order. The gender of the respondent plays an important role in categorization of some attributes. Using the importance–performance analysis, we identify the attributes where the foodservice provider should maintain a high performance or where improvement is required. Improvements in some attributes are difficult due to foodservice provider's self-assessment of high performance or high difficulty for improvement.Originality/valueIn this study, we examine the importance of various foodservice attributes among undergraduate residential students. We combine multiple methods of Kano categorization to compute importance values of the attributes. We also investigate the reasons behind the gap between student's and foodservice manager's perception of the performance of these attributes.
