“…Weft knitting, so far, has proven to be the most versatile method when it comes to 3D knitting 31 . Regarding machine type, the flatbed machines are superior over the circular knitters as they can provide multiple types of tubes and enable rib transfer, thus variations in the width and circumference of 3D forms may be achieved ( Figure 10 ).…”

Knitting is a versatile technology which offers a large portfolio of products and solutions of interest in heart valve (HV) tissue engineering (TE). One of the main advantages of knitting is its ability to construct complex shapes and structures by precisely assembling the yarns in the desired position. With this in mind, knitting could be employed to construct a HV scaffold that closely resembles the authentic valve. This has the potential to reproduce the anisotropic structure that is characteristic of the heart valve with the yarns, in particular the 3-layered architecture of the leaflets. These yarns can provide oriented growth of cells lengthwise and consequently enable the deposition of extracellular matrix (ECM) proteins in an oriented manner. This technique, therefore, has a potential to provide a functional knitted scaffold, but to achieve that textile engineers need to gain a basic understanding of structural and mechanical aspects of the heart valve and in addition, tissue engineers must acquire the knowledge of tools and capacities that are essential in knitting technology. The aim of this review is to provide a platform to consolidate these two fields as well as to enable an efficient communication and cooperation among these two research areas.

“…Therefore, the number of vehicles entering the leg intersection per second ( ) is obtained by using data from other intersection which is taken from the number of vehicles coming out from the other intersection then entering one of the leg of the main intersections [6,7,8,9]. The intersection is M.H.…”

Traffic congestion has become a serious problem in Indonesia, especially in Jakarta city. The main problem occurs at intersections. One of the solutions that can be proposed to reduce congestion at the intersection is to implement traffic signal control strategy at the intersection. Levels of congestion are determined by the queue length of vehicles. Green time (Tg) and red time (Tr) are determined by the queue length on each of the intersection leg. The lowest congestion level is represented by the smallest value of queue length. Optimization is performed in order to find an optimal value of green time (Tg), such that the queue length of vehicles becomes the smallest in constant cycle time. Due to the cycle time (Tn) is constant and the intersection is controlled in 2 phases, the variable needed to be optimized is only the green time (Tg). The red time (Tr) can then be counted from the cycle time (Tn) minus the green time (Tg).
