Irrationality is needed to compute with signal machines with only three speeds

International audienceSpace-time diagrams of signal machines on finite configurations are composed of interconnected line segments in the Euclidean plane. As the system runs, a network emerges. If segments extend only in one or two directions, the dynamics is finite and simplistic. With four directions, it is known that fractal generation, accumulation and any Turing computation are possible. This communication deals with the three directions/sp eeds case. If there is no irrational ratio (between initial distances between signals or between speeds) then the network follows a mesh preventing accumulation and forcing a cyclic behavior. With an irrational ratio (here, the Golden ratio) between initial distances, it becomes possible to provoke an accumulation that generates infinitely many interacting signals in a bounded portion of the Euclidean plane. This b ehavior is then controlled and used in order to simulate a Turing machine and generate a 25-state 3-speed Turing-universal signal machin

Online Marketplace Characteristics for Freelance Designers

Marketplace is one of the choice places for designers to market the products they create. Online Marketplace is a networking site or application on a gadget that provides online trading facilities from various sources. In the marketplace, application owners or website networks only provide facilities for users to display products sold. In addition, the marketplace owner also provides facilities in the form of bridging online transactions between sellers (designers) and buyers. In utilizing the marketplace, designers must know the needs and desires and design market trends. Because with accurate data related to needs, trend design will greatly help designers to create design products that are suitable for the market. Not only the idealism of designers in making works, but also still relies on dynamically changing demands. This study intends to determine the design trends that are in accordance with the desires and needs of the graphic design market so that they can help designers determine the making of works sold in the marketplace. This study uses a qualitative research approach to explore all phenomena that occur in the world of online design marketplace. Through this qualitative approach, researchers will understand social reality, see what conditions exist in the sale and purchase of design products and design trends that are popular in society. This qualitative approach is sought to be directed at identifying the trend design and style design that designers need for the basis of making designs that can be sold in the marketplace.   Keywords: Online Marketplace, Design Marketplace, Freelance Designe

Semantic Interpretation in Experimental Typography Creation

This research aims to reveal how to design by utilizing semantics to reinforce the meaning of a message through typography. The methods used in this research are: exposing, redefining, managing, prototyping, and trendspotting. The experiment was carried out by changing the nouns, verbs, and adjectives from the letters of the alphabet into visual semantics without changing the meaning of the words used. Semantic design for typography can be used by changing one or more letters into a visual form that still conveys the meaning and nature of the words used. The result of this study is the design of semantic interpretation in typography that strengthens and clarifies meaning. Design can be applied in turning letters into illustrative forms, whether it only uses one letter in a word or can also use more than one letter to strengthen the meaning of a word.

Collaboration Between Typography and Visual Narrative to Strengthen the Communication Delivery Process

Visual narrative (also called visual storytelling) is a story told primarily through visual media. The story can be described using photography, illustrations, or video. It can be enhanced with graphics, music, sound, and other audio. In comparison, typography is the study of letters and their relation to the delivery of information. This study aimed to examine how visual communication carried out through visual narrative can be more quickly understood by the public when combined with the communicative power of typography. Two tactics were employed: 1) A/B testing, which involved using several images to test the effectiveness of the image or design; and 2) eye tracking, which tested how the audience read in digesting the information from the designs that were created. Recommendations and a formulation of work steps/processes that use a combination of typography and visual narrative to increase the effectiveness of delivering messages to the audience were developed. Keywords: typography, visual narrative, communication delivery, strengthen proces

Virtual small business entrepreneurship opportunities

For small business entrepreneurs in rural areas to survive in the digital contexts, research is essential on the challenges they face and how these challenges can become opportunities for other entrepreneurs. In this study, small business entrepreneurship opportunities at a township in the Eastern Cape were explored. The basis of the study was that entrepreneurship opportunities are embedded in business challenges and entrepreneurs who can provide services or products that address identified challenges can have viable entrepreneurship ventures. The study used two-phased sequential interviews to collect data to address the purpose of the study, which was: to explore the small business entrepreneurship opportunities in the Eastern Cape in the context of digitalisation. In the first interview challenges, faced by 60 entrepreneurs at an identified small business Mall, were recorded, and the most common challenges were noted. After noting the most common challenges and suggestions for possible business opportunities, associated with addressing the challenges, interviews with eight entrepreneurs in the Mall were then undertaken to gather more information. The study found evidence that small business entrepreneurship opportunities existed in areas related to providing essential support services, such as small business education and training, infopreneurship, and digital infrastructure retailing including providing alternative power options, such as solar power for the enterprises. With the high unemployment and high rate of small business failure, the study recommends the effective exploitation of the identified business opportunities to ensure that existing enterprises survive and new ventures also arise
