This article explores the use of innovative strategies in improving learners' ability to create simple dialog among Grade 8 learners at SMP Muhammadiyah 2 Taman Sidoarjo. The main focus of this research is to apply project-based learning model combined with guided conversation technique in learning the material of asking and giving opinion. Project-based learning as a learning model aims to stimulate the activeness, creativity of students in completing the learning. Learners are guided to create text in the form of a simple dialog with the theme of asking and giving opinion and then practiced with peers. By using guided conversation techniques, learners are guided intently to achieve learning objectives. Learning begins with the use of ice breaking relevant to the material, triggering questions, video footage, imitating conversations based on the text that has been provided until the practice of making conversations is a form of guidance to students. The research method applied in this study carries a combinative approach between project-based learning models with guided conversation techniques. The observation results showed a significant increase in students' active participation during the learning process. Students were more actively involved in group discussions, questions, and assignments. They are not only the recipients of information, but also the main actors in their own learning. This increased participation indicates that the models and techniques used are able to create a learning environment that stimulates more intensive student engagement. The conclusion we can draw is that this innovative strategy proves that the use of project-based learning model with guided conversation technique can be an effective step in improving learners' ability in the creation of speaking text in English language learning.

Experimental study on ice breaking by a cavitating water jet in a Venturi structure

Ice breaking by a cavitating water jet based on Venturi structure is studied experimentally. Systematic researches of cavitating water jet interacting with ice are carried out by doing indoor experiments, where the cavitating jet is generated by a tailor-made device through Venturi nozzle and the circular fresh-water ice plates are made of boiled water in a cryostat. The whole evolution of cavitating jets and ice plates is recorded by two high-speed cameras from two views simultaneously. Pressure loads on the rigid wall of cavitating water jet is compared with that of conventional non-cavitating water jet and the change is analyzed. Among two typical structural parameters of Venturi cavitating nozzles selected in this paper, the ratios of throat length to diameter ε (1; 1.5; 2) and the diverging angles α (8°; 10°; 12°), the nozzle withε = 1 andα = 12° is found to be the best in terms of loads on wall. On this basis, the responses of ice plate, including crack generation, crack development and fracture, are studied under the cavitating jet loads, mainly involving the compressible pressure P1 and cavitation pressure Pc. According to the main cause and propagation sequence of cracks, the failure mechanisms of ice under Venturi cavitating jet can mainly be divided into three types: shock waves failure, overall strength failure and local strength failure, along with six damage patterns roughly. Furthermore, the effects of ice plate thickness, cavitating water jet strength and boundary conditions are also investigated.

Motion of a submerged body under a free surface and an ice cover in finite water depth conditions

In this study, we consider the motion of a submerged body near the free surface of a liquid and a liquid covered with an ice cover in finite water depth conditions. The influence of water depth on the nature of motion of a submerged body has been experimentally and theoretically analysed. The experiments were performed in an ice tank. The use of a cable towing system allowed the researchers to measure the magnitude of the relative vertical displacement of the submerged body resulting from the action of the lift force. The influence of ice cover on the relationship between the vertical displacement, trim angle, criterion for ice breaking, and speed of movement of the submerged body model was established. For theoretical research, the ice cover was modelled by a viscoelastic floating plate, and the submarine was modelled by a source–sinks system in a fluid flow. The influence of water depth, the presence of an ice cover, changes in the submergence depth, and the speed of movement of the submerged body on the wave resistance, lift force, and trimming moment were analysed. Theoretical results are supported by experimental data.

Simulation of Sea Ice Fragmentation Based on an Improved Voronoi Diagram Algorithm in an Ice Zone Navigation Simulator

In order to reduce the cost of navigation training in the waters of ice zones and improve the effectiveness of the training process, a method for simulating sea ice fragmentation in an ice zone navigation simulator is proposed. The Voronoi diagram algorithm, which takes the ice thickness into account and affects the degree of fragmentation, was used to preprocess the sea ice model so that the number and sizes of the ice model fragmentations would be related to the ice thickness. According to the position of the preprocessed sub-blocks of the ice model, the collision bodies of the Mesh Collider and Sphere Collider were set up to realize the effect of the conduction of ice cracking as a result of the ship’s hull colliding with the ice surface. Based on the positional relationship between mesh triangle elements and the water surface, the volume of an ice floe that should have been underwater when it reached equilibrium was calculated to achieve the sea-floating effect of the broken ice floe. The quadtree method for the management of sea ice scenes was improved to improve the timeliness of the replacement of the ice model. The experiments show that this method improved the realism of simulations of sea ice breaking in ice zones and can be used for simulations in ice zone navigation simulators.

Nonlinear gravity waves in the channel covered by broken ice

The two-dimensional nonlinear problem of a steady flow in a channel covered by broken ice with an arbitrary bottom topography including a semi-circular obstruction is considered. The mathematical model is based on the velocity potential theory accounting for nonlinear boundary conditions on the bottom of the channel and at the interface between the liquid and the layer of the broken ice, which are coupled through a numerical procedure. A mass loading model together with a viscous layer model is used to model the ice cover. The integral hodograph method is employed to derive the complex velocity potential of the flow, which contains the velocity magnitude at the interface in explicit form. The coupled problem is reduced to a system of integral equations in the unknown velocity magnitude at the interface, which is solved numerically using a collocation method. Case studies are conducted both for the subcritical and for the supercritical flow regimes in the channel. For subcritical flows, it is found that the ice cover allows for generating waves with amplitudes larger than those that may exist in the free surface case; the ice cover prevents the formation of a cusp and extends the solution to larger obstruction heights on the bottom. For supercritical flow regimes, the broken ice significantly affects the waveform of the soliton wave making it gentler. The viscosity factor of the model apparently governs the wave attenuation.

Ice breaking by low-velocity impact with a rigid sphere

Penetrator–ice plate impact subjected to dynamic loading constitutes many scientific applications for ice, such as controlling ice disasters by penetrating the ice cover and then entering underwater to explosive ice breaking on Earth, and life detection and resource development under water ice sheet on outer space planets. We present experimental results of brittle damage induced by a small spherical projectile impacting an ice plate with a thickness of 6–50 mm using a drop ball test device or a vertical gas gun. The corresponding impact velocities vary from 2 to 74 m/s. Crater parameters, residual velocity and energy absorption are investigated and assessed. The main fracture patterns and crater formation are captured by two high-speed cameras. A dynamic recrystallization phenomenon of polycrystalline ice is observed, and its formation mechanism is preliminarily analysed. The effects of the impact velocity, ice sample thickness, and restriction conditions on dynamic fracture processes and failure modes are systematically explored. These results improve our understanding of dynamic fracturing mechanism in ice engineering applications.

An Effectiveness of Group Model Coaching for Improving Life Balance Among Youth

Life imbalanced amongst youth regarding moral, behaviour and personality problems have been discussed in many studies. However, not many of these research articles discussed on effective interventions process to improve the imbalance especially on youth life. Hence, this study offers a methodology on conducting an effectiveness intervention to improvise youth life-balance. A group of 90 youths were selected from a secondary school to participate the intervention process based on their low academic performance. First phase of the intervention was to investigate the imbalanced elements using a modified Wheel of Life which consisted of 8 elements with 10-points scale. During the investigation session, youth are required to shed the modified Wheel of Life based on individual perspective. The coach analysed all the 90 shaded Wheel of Life and found that personality and discipline element has the lowest score. Then, only 9 youth that having lowest score in this element are grouped and proceed to second phase which is called coaching session. In this session, the youth have undergone 5 interaction sessions where the first session is known as ice breaking activity then followed by another 4 interactions coaching sessions using GROUP model approach. The purpose of ice breaking session was to gain rapport amongst youth. Then during the GROUP model coaching session, a pre and post coaching forms were prepared and filled by the youth to gauge their life balance status. These GROUP model coaching sessions continued until the fourth session. Then, the pre and post coaching forms were analysed to quantify the impact of the coaching sessions on the youth personality and discipline element. For the last phase, the results of these coaching sessions were validated through the interview session with the teachers and parents of the youth. It was found that the average effectiveness percentage of the GROUP model coaching is 72.95%. It is hope that this study contributes new knowledge on intervention process to improvise youth life balance.

Numerical investigation of ice plate fractures upon rigid ball impact

The fracture process and breaking capability of ice cover impacted by high-speed projectiles before underwater explosion is an urgent subject of scientific research in ice engineering applications. This paper presents the results of numerical simulations of the dynamic fracture behaviour induced by the impact of a small spherical projectile on an ice plate. The proposed 3D rate-dependent peridynamics model is validated by the dynamic ring Brazilian disc testing of ice specimens. Good agreements between the present model and the previous experiments are obtained in ice breaking processes and damage patterns of thin, medium and thick ice plates. Several cases are analysed and discussed in terms of various impact velocities, ice thicknesses, and boundary constraint conditions. The simulations identify detailed fracturing characteristics that are not observed in experiments, including the sequence and shape of crack propagation in a short time interval, the crater formation and the damage evolution along the thickness direction. The proposed peridynamics computational model provides new understanding of the potential of using penetrator–ice block impact tests to observe the evolution of complex brittle damage and reveal the failure mechanism.
