This textbook presents the principles of functional analysis in a clear and concise way. The first three chapters describe the general notions of distance, integral, and norm, as well as their relations. Fundamental examples are provided in the three chapters that follow: Lebesgue spaces, dual spaces, and Sobolev spaces. Two subsequent chapters develop applications to capacity theory and elliptic problems. In particular, the isoperimetric inequality and the P lya-Szegő and Faber-Krahn inequalities are proved by purely functional methods. The epilogue contains a sketch of the history of functional analysis in relation to integration and differentiation. Starting from elementary analysis and introducing relevant research, this work is an excellent resource for students in mathematics and applied mathematics.
The basic structures of linear functional analysis: Banach spaces, Hilbert spaces, locally convex topological vector spaces. Examples of spaces of functions and function-like objects: Lebesgue spaces, Sobolev spaces, spaces of holomorphic functions, spaces of distributions. Bounded linear operators. The standard classical theorems: Hahn-Banach, open mapping, closed graph, Banach-Steinhaus, Bourbaki-Alaoglu, nonemptyness of the spectrum, elementary properties of the resolvent. Spectral theory of compact operators. Applications to eigenfunction expansions. The Schauder fixed point theorem. Extreme points of convex sets in locally convex spaces and the Krein-Milman theorem. Elementary facts about Hilbert spaces.
Functional Analysis and Allocation is a top-down process of translating system-level requirements into detailed functional and performance design criteria. The result of the process is a defined Functional Architecture with allocated system requirements that are traceable to each system function.
The initial step is to identify the lower-level functions required to perform the various system functions. As this is accomplished, the system requirements are allocated and functional architecture(s) are developed. These activities track and interact so that as details evolve, they are continually validated against each other. Should anomalies occur, alternate architectures and allocations may be carried through early stages of this activity until the optimum approach becomes apparent. The internal and external functional interfaces are defined as the architecture matures. The functional architecture(s) and their companion functional requirements are the input to the Synthesis activity. Completing the Design Loop, the detailed results of the Synthesis are compared to the candidate architecture(s) and allocated requirements to help zero in on the optimum approach and to assure that all proposed solutions meet established requirements. [1]Decomposition: to lower-level functions is the incoming interface for the Requirements Loop. The functions identified in the Requirements Analysis are analyzed to define successively lower-levels of functions that accomplish the higher-level functional requirements. Alternate lower-level functional solutions covering all anticipated operating modes are proposed and evaluated to determine which provides the best fit to the parent requirements and the best balance between conflicting ones. The initial decomposition is the starting point for the development of the functional architecture and the allocation of requirements to the lower functional levels. Adjustments to the decomposition strategy may be necessary as details are developed. [1]
Functional programming is becoming increasingly widespread in industry. This trend is driven by the adoption of Scala as the main programming language for many applications. Scala fuses functional and object-oriented programming in a practical package. It interoperates seamlessly with both Java and Javascript. Scala is the implementation language of many important frameworks, including Apache Spark, Kafka, and Akka. It provides the core infrastructure for sites such as Twitter, Netflix, Zalando, and also Coursera.

The text would be an appropriate resource for the first three semesters of most undergraduate music theory sequences. It is structured in four parts: music fundamentals, functional harmony, chromatic harmony, and form. Chapters are well written, concise, and focus on stylistic characteristics of Western Tonal Music. Musical examples are drawn from the familiar canon and less familiar sources, including many from women composers, and the online version of the text includes MIDI audio for each example. Students will also find hyperlinks in the text a useful study aid. Exercises are interspersed throughout each chapter and though these are appropriate; an instructor may wish to supplement them to help students gain mastery of concepts.
Revisions to the text and errata corrections are listed at the end of the text. As for the content, there is not much to be discussed regarding accuracy. I think many instructors will appreciate the discussion of diatonic interval successions and their use in two-voice counterpoint/motion (e.g., parallel, oblique, contrary). This common-sense approach teaches the student intervals and the resolution of pitches, paving the way for the study of functional harmony instead of focusing on intervals as an abstract concept or in the context of learning strict counterpoint.
From a research standpoint, functional assessments provide supporting evidence to develop, improve and attest to different evidence-based treatments. In the clinical setting, these instruments are commonly used to set rehabilitation goals, to develop specific therapeutic interventions and to monitor clinical changes.3
In 2014, functional assessments took a different direction when the Improving Medicare Post-Acute Care Transformation Act of 2014 (the IMPACT Act) was signed into law seeking to connect findings on the baseline assessment to functional outcomes. This required that Long-Term Care Hospitals (LTCHs), Skilled Nursing Facilities (SNFs), Home Health Agencies (HHAs) and Inpatient Rehabilitation Facilities (IRFs) to report and submit standardized patient assessment data, including quality measures and standardized patient assessment data elements. The collection of this information permitted the exchange of information among providers on specific functional domains that included functional status, cognitive function, and mental status among some. The final goal intended to enhanced rehabilitation outcomes through share decision making, care coordination and improved discharge planning.4
Activities of daily living (Table 1A) measures the performance of basic functional skills required to care for oneself independently. They measure basic daily activities (eating, grooming, bathing, dressing, continence) mobility (gait, transfers) and cognition. Examples include 5:
Pain functional assessments (Table 7) assist in evaluation of the severity of pain, how effective treatment interventions have been, and the presence of associated psycho-emotional/behavioral components. Examples include 5:
Work Related Injuries (Table 8): Standardized functional assessment that globally evaluates functional tolerance (based on a medical condition) that is safe for the worker to perform. Examples of these are2:
With the advancement of technology has come the possibility to perform functional assessments in new ways, therefore research is being developed to design new functional assessment tools that might provide accurate, valid, reliable and tangible data.8
The assessment of any patient with a functional impairments regardless of the etiology should try to quantify such impairment taking into consideration physical, cognitive, behavioral, structural, environmental and social barriers. It is important to note the complexity of the population due to the multiple subspecialties within the field, such as spinal cord injury, brain injury, palliative care, pediatric, pain management, sport medicine, cardiopulmonary rehabilitation. This diversity calls for a complex, detailed approach with a wide range of required skills and knowledge unique to those areas and with the primary goal of restoring function as well as independence. Standard components of a physiatrist history include chief complaint, history of present illness, allergies, medications, review of system, past/family/psychosocial history, functional history (at home, community, work current and prior to the illness). Emphasis on motor skills(bed mobility, transitional mobility, ambulation, coordination, balance), activity of daily living(bathing, dressing, grooming, toileting, feeding), cognition (alertness, orientation, memory, ability to encode new information, communication, etc.), vocational (current, past and future) and use of assistive devices/technology.10 Comprehensive functional assessment evaluations must reflect appropriate medical record documentation that justify the need for the rehabilitation services and evidence the improvement during those interventions. 041b061a72
