A hybrid analytical-numerical solution is proposed to solve the problem of a laterally loaded pile with a circular cross-section in multilayered soils. In the pile-soil model, the lateral load is located at the pile head including both lateral force and bending moment. The single pile is considered as a beam on elastic foundation while shear beams model the soil column below the pile toe.

The motion equation of a one-degree-of-freedom system when subjected to earthquakes is usually not solved by analytic methods. This problem can only be solved through the time step method, when integrating differential equations. This paper is devoted to presenting a numerical solution for a seismic analysis problem of a highway bridge pier with high damping rubber bearings under earthquakes.

The general policy implication is that environmental policies should not be uniform for all countries. Environmental policy must be country‐and polluter‐specific to solve environmental problems faced by a country. A well‐designed environmental policy should reflect the specific needs of a country, considering the country’s level of economic development as well as specific environmental pollutants.

The purpose of this study was to explore of the role of language switching in a group of Iranian bilingual students while they were involved in mathematical problem solving. Language switching has been viewed as a common practice in bilingual students in their classroom, particularly for mathematics learning. In bilingual students, using their first language to solve at least part of a problem may facilitate mathematical thinking and lead to a successful problem solving process.

This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

The thesis studied the development and implementation of the conceptual Continuous Improvement Teamworking (CIT) Model for strategic performance improvement in retail banking operations. The investigation using of a dominant qualitative to a Less-dominant quantitative approach as a mixed-method strategy revealed the importance of the CIT Model realised through the CTIO (Concern-Task-Interaction-Outcome) Problem-Solving Cycle. The CTIO Cycle is a variant form of the traditional Deming-Shewhart PDCA (Plan-Do-Check-Action) Cycle.
