Abstract
Purpose
This study aims to treat a novel system of Volterra integro-differential equations with multiple delays and variable bounds, constituting a generic numerical method based on the matrix equation and a combinatoric-parametric Charlier polynomials. The proposed method utilizes these polynomials for the matrix relations at the collocation points.
Design/methodology/approach
Thanks to the combinatorial eligibility of the method, the functional terms can be transformed into the generic matrix relations with low dimensions, and their resulting matrix equation. The obtained solutions are tested with regard to the parametric behaviour of the polynomials with $\alpha$, taking into account the condition number of an outcome matrix of the method. Residual error estimation improves those solutions without using any external method. A calculation of the residual error bound is also fulfilled.
Findings
All computations are carried out by a special programming module. The accuracy and productivity of the method are scrutinized via numerical and graphical results. Based on the discussions, one can point out that the method is very proper to solve a system in question.
Originality/value
This paper introduces a generic computational numerical method containing the matrix expansions of the combinatoric Charlier polynomials, in order to treat the system of Volterra integro-differential equations with multiple delays and variable bounds. Thus, the method enables to evaluate stiff differential and integral parts of the system in question. That is, these parts generates two novel components in terms of unknown terms with both differentiated and delay arguments. A rigorous error analysis is deployed via the residual function. Four benchmark problems are solved and interpreted. Their graphical and numerical results validate accuracy and efficiency of the proposed method. In fact, a generic method is, thereby, provided into the literature.

Abstract
With the advent of technology and science, the business environment will keep changing very fast. Today, Information Technology (IT) is used in almost all business applications. The most important improvements are being realized at the management side since IT is fully supporting decision-making processes now. Human Resources Management (HRM) is being affected by IT such as web-based technologies and intelligent systems and these systems make HRM much more effective. Today’s HRM-related software do not deal with just payrolls, they also include recruiting and record-keeping, training and performance appraisal which have transitioned HRM from task-oriented to people-oriented. Today, Human Resources Information Systems (HRIS) and electronic HRM (e-HRM) are being utilized by many organizations all over the world and play a strategic role in decision-making processes for effective and efficient HRM. This study investigates the recent literature on HRIS, e-HRM and Decision Support Systems in HRM to identify the improvements and debates on contemporary Human Resources Management.

Abstract
This chapter introduces human resource practices in contemporary knowledge-based organizations of today’s fast moving sectors. Such organizations are called ‘knowledge intensive firms’ (KIFs) which are distinct from traditional organizations as their main focus is innovation. These firms employ knowledge-oriented workers named as ‘knowledge workers’ (KWs) whose main task is to find creative solutions to complex problems and create new knowledge. Knowledge workers are well-educated experts and their nature of work includes complexity, creativity and analytical thinking. Such workers are the most important resource of KIFs, as they own the means of production. In this regard, attracting, retaining and motivating KWs have become crucial for knowledge intense firms to gain competitive advantage. Having these workers in hand, human resource management practices also differ in knowledge-oriented organizations. This chapter aims to introduce such contemporary practices and inform the reader about the strategies in attracting, retaining and motivating KWs in organizations.

Abstract
Purpose
The purpose of this paper is to rise the autonomous flight performance of the small unmanned aerial vehicle (UAV) using simultaneous tailplane of UAV and autopilot system design.
Design/methodology/approach
A small UAV is remanufactured in the UAV laboratory. Its tailplane can be changed before the flight. Autopilot parameters and some parameters of tailplane are instantaneously designed to maximize autonomous flight performance using a stochastic optimization method. Results found are applied for simulations.
Findings
Benefitting simultaneous tailplane of UAV and autopilot system design process, autonomous flight performance is maximized.
Research limitations/implications
Authorization of Directorate General of Civil Aviation in Turkey is required for UAV flights.
Practical implications
Simultaneous tailplane and autopilot system design process is so useful for refining UAV autonomous flight performance.
Social implications
Simultaneous tailplane and autopilot system design process fulfills confidence, high autonomous performance, and easy service demands of UAV users. By that way, UAV users will be able to use better UAVs.
Originality/value
Creating a novel technique to recover autonomous flight performance (e.g. less overshoot, less settling time and less rise time during trajectory tracking) of UAV and developing a novel procedure performing simultaneous tailplane of UAV and autopilot system design idea.
