An exploration of solutions to two related Hofstadter-Huber recurrence relations
(Pergamon-Elsevier Science Ltd, 2020)In this study, we explore the properties of certain solutions of two Hofstadter-Huber recurrence relations. The first is Hofstadter's V-recurrence, which is defined by the nested recurrence relation V(n) = V(n - V (n - 1)) ... -
On a conjecture about generalized Q-recurrence
(Sciendo, 2018)Chaotic meta-Fibonacci sequences which are generated by intriguing examples of nonlinear recurrences still keep their mystery although substantial progress has been made in terms of well-behaved solutions of nested ... -
On a Generalization of Hofstadter's Q-Sequence: A Family of Chaotic Generational Structures
(Wiley-Hindawi, 2018)Hofstadter Q-recurrence is defined by the nested recurrence Q(n) = Q(n - Q(n - 1)) + Q(n - Q(n - 2)), and there are still many unanswered questions about certain solutions of it. In this paper, a generalization of Hofstadter's ... -
The key for success in enterprise information systems projects: development of a novel ERP readiness assessment method and a case study
(Taylor & Francis Ltd, 2020)ERP projects have a significant cost-share with high failure-rates. When the failure factors of ERP projects are evaluated, it is noteworthy that enterprises do not pay enough attention to ERP Readiness and moved directly ... -
Multi-Purpose Tugboat/Aht Selection For Northern Caspian Sea With Topsis and Moora Methods
(2019)A large part of the world energy requirement is provided from offshore oil and gas fields. The Kashagan site in the Northern Caspian Sea has one of the largest known reserves and marine operations are important for the ... -
On the Selection of Ship Wastewater Treatment Plant Incorporating Analytical Hierarchy Process With 0-1 Goal Programming
(2019)As a result of the continuous pollution of the air, seas and soil, the deterioration of the natural equilibrium can be felt severely. Therefore, the prevailing vision of sustainable environment is frequently mentioned in ... -
On a recursively defined sequence involving the prime counting function
(University of Waterloo, 2021)We prove some properties of sequence A335294 from the On-Line Encyclopedia of Integer Sequences, defined by an = ?(n) - ?(?n-1 k=1ak), where ?(x) is the number of primes ? x. In particular we show that the sequence (an) ... -
Process development in customer order information systems to gain competitive advantage: A SME case study
(Inderscience Publishers, 2016)In today's intensely competitive business environment improvement in sales order cycle time is vital for the company's success. Controlling credits and measuring payment, especially crucial for a SME to manage its cash ... -
Yard block assignment, internal truck operations, and berth allocation in container terminals: introducing carbon-footprint minimisation objectives
(Palgrave Macmillan Ltd, 2021)It is of increasing importance to carry out port terminal operations in an environmentally sustainable way. We approach the yard block assignment and internal transportation problem in a way that establishes an optimum ... -
