EyePhone Technology: A Smart Wearable Device

In the past few decades, wearable sensors and devices have evolved into central technologies that have significantly impacted next-generation healthcare solutions in the previous decade. It is an age of incredibly cut-throat competition, even the youth. This technology is Hand-free, eyephone-operated telephone technology. It measures where the user’s eyes are located on the phone’s display employing a camera attached to the device. The typical work the eye bones assigned to eye tracking, eye blinking, detecting, etc., by way of eye-tracking, users can take care of their email, calendar, phone, etc. The leading technologies in use are a Human-Computer Interface (HCI) and a Human Phone Interface (HPI). It helps those with disabilities greatly. The IT Index is an expanded form of HCI. The use of mobile devices like smartphones and tablets is on the rise, and, to some extent, it could displace the use of desktops and laptops. Human-computer interaction is interested in the interaction between people and the computer system and between software and applications. Our focus is on this revolutionary new type of technology called the eye-phone.

On the Implicit Equation of Conics and Quadrics Offsets

A new determinantal representation for the implicit equation of offsets to conics and quadrics is derived. It is simple, free of extraneous components and provides a very compact expanded form, these representations being very useful when dealing with geometric queries about offsets such as point positioning or solving intersection purposes. It is based on several classical results in “A Treatise on the Analytic Geometry of Three Dimensions” by G. Salmon for offsets to non-degenerate conics and central quadrics.

Animation Narrative in Vertical Format

Animation, defined as a process utilized to suggest motion to image or drawings, has evolved towards different techniques and styles offered by the industry. Its esthetic nature meets a progressive technologization of art and creativity, and therewith it responds to esthetics enrichment not only in animated object, but also in its creation process. The possibility to have an expanded form in techniques and formats has therefore prompted it to explore and to enrich various elements of its visual narrative. One of the most prominent elements has been the application of vertical format, while also acknowledging the consumption of digital content in smartphones. MOJITO LAB of ARPA/BUAP has focused on this technique as a line of research for 2D animation. This article herein presents some areas with considerable interest in the impact of vertical format in animation as follows: 1) The antecedents of vertical format in both still and moving image; 2) the relation between vertical format and digital media generated by smartphones; 3) observations based on the image analysis of 2D animation utilizing vertical format which provides esthetic qualities to visual narrative language of 2D animation.

Merchant Networks

This chapter provides three microstudies on real-life examples of merchant networks in operation. The first microstudy is the Cairo-based Jewish merchants' network, whose records from the tenth through twelfth centuries were preserved in the Geniza and represents, in its India segments, a simple and thin network. Next is the Armenian network centered in New Julfa from the seventeenth through eighteenth centuries that represents the epitome of the merchant network in its most sophisticated, elaborated, and expanded form. Finally, the Sephardic Jewish network based in Livorno in the eighteenth century that exemplifies the marginalization of the network in the shadow of the corporation. The three microstudies provide a taste of some episodes in the rise and decline of merchant networks.

Active Metal Template Synthesis and Thermal Actuation of a Nanohoop [c2]Daisy Chain Rotaxane

<p>Molecules and materials that demonstrate large amplitude responses to minor changes in their local environment play an important role in the development of new forms of nanotechnology. Molecular daisy chains are a type of a mechanically interlocked molecule that are particularly sensitive to such changes where, in the presence of certain stimuli, the molecular linkage enables muscle-like movement between a reduced-length contracted form and an increased-length expanded form. To date, all reported syntheses of molecular daisy chains are accomplished via passive-template methods, resulting in a majority of structures being switchable only through the addition of an exogenous stimuli such as metal ions or changes in pH. Here, we describe a new approach to these structural motifs that exploits a multi-component active-metal template synthesis to mechanically interlock two pi-rich nanohoop macrocycles into a molecular daisy chain which we show can be actuated through simple thermal changes.</p>
