Predicting Hospital Readmissions using Patient Data:
Developing machine learning models to predict the likelihood of a patient being readmitted to the hospital within 30 days of discharge can help hospitals improve care coordination and reduce healthcare costs. A student could collect historical patient data like demographics, medical diagnoses, procedures/surgeries performed, medications prescribed upon discharge, rehabilitation services ordered etc. Then build and compare different classification algorithms like logistic regression, decision trees, random forests etc. to determine which features and models best predict readmission risk. Evaluating model performance on a test dataset and discussing ways the model could be integrated into a hospital’s workflow to proactively manage high-risk patients post-discharge would make this an impactful project.

Auto-detection of Disease from Medical Images:
Medical imaging plays a crucial role in disease diagnosis but often requires specialized radiologists to analyze the images. A student could work on developing deep learning models to automatically detect diseases from different medical image modalities like X-rays, CT scans, MRI etc. They would need a large dataset of labeled medical images for various diseases and train Convolutional Neural Network models to classify images. Comparing the model’s predictions to expert radiologist annotations on a test set would measure how accurately the models can detect diseases. Discussing how such models could assist, though not replace, radiologists in improving diagnosis especially in areas lacking specialists would demonstrate potential impact.

Precision Medicine – Genomic Data Analysis for Subtype Detection:
With the promise of precision medicine to tailor treatment to individual patient profiles, analyzing genomic data to identify clinically relevant molecular subtypes of diseases like cancer can help target therapies. A student could work on clustering gene expression datasets to group cancer samples into molecularly distinct subtypes. Building consensus clustering models and evaluating stability of identified subtypes would help establish their clinical validity. Integrating clinical outcome data could reveal associations between subtypes and survival. Discussing how the subtypes detected can inform prognosis and guide development of new targeted therapies showcases potential impact.

Clinical Decision Support System for Diagnosis and Treatment:
Developing a clinical decision support system using electronic health record data and clinical guidelines can help physicians make more informed decisions. A student could mine datasets of patient records to identify important diagnostic and prognostic factors using feature selection. Build classifiers and regressors to predict possible conditions, complications, treatment responses etc. Develop a user interface to present the models’ recommendations to clinicians. Evaluating the system’s performance on test cases and getting expert physician feedback on its usability, accuracy and potential to impact diagnosis and management decisions demonstrates feasibility and impact.

Population Health Management Using Claims and Pharmacy Data:
Analyzing aggregated de-identified insurance claims and pharmacy dispense data can help identify high-risk populations, adherence issues, costs related to non-evidence based treatments etc. A student could apply unsupervised techniques like clustering to segment the population based on demographics, clinical conditions, pharmacy patterns etc. Build predictive models for interventions needed, healthcare costs, hospitalization risks etc. Discuss ways insights from such analysis can influence public health programs, payer policies, and help providers manage patient panels with proactive outreach. Demonstrating a pilot with key stakeholders establishes potential population health impact.

Precision Nutrition Recommendations using Personal Omics Profiles:
Integrating multi-omics datasets encompassing genetics, metabolomics, nutrition from services like 23andMe with self-reported lifestyle factors offers a holistic view of an individual. A student could collect such personal omics and phenotypes data through surveys. Develop models to generate tailored nutrition, supplement and lifestyle recommendations. Validate recommendations through expert dietician feedback and pilot trials tracking outcomes like weight, biomarkers over 3-6 months. Discussing ethical use and potential to prevent/delay onset of chronic diseases through precision lifestyle modifications establishes impact.

As detailed in the examples above, impactful machine learning capstone projects in healthcare would clearly define a problem with strong relevance to improving outcomes or costs, analyze real and complex healthcare datasets applying appropriate algorithms, rigorously evaluate model performance, discuss integrating results into clinical workflows or policy changes, and demonstrate potential to positively impact patient or population health. Obtaining stakeholder feedback, piloting prototypes and establishing generalizability strengthens the discussion around potential challenges and impact.

The prototype demonstrated an elegant, easy-to-use technical solution that could one day help address a real social issue if further refined and marketed by the company.

Engineering Capstone: A mechanical engineering student consulted with engineers at an electric vehicle manufacturer to help improve the battery cooling system design in their upcoming model. Through computational analysis and laboratory testing, she evaluated alternative heat exchanger designs, coolant flow paths and thermodynamic models to identify the most energy and cost-efficient configuration. Her recommended design changes were estimated to provide a 10% increase in battery thermal management performance while lowering component costs. The company was so impressed they offered her a job after graduation to help implement her improvements in the production phase.

Social Work Capstone: A social work major collaborated with a state child welfare agency seeking ways to minimize placement disruptions and better support foster family stability. Through interviews and surveys of foster parents, social workers and child welfare administration, she pinpointed organizational barriers hindering continuity of care such as high caseloads, lack of foster parent training and delays in licensing approval. Her capstone paper proposed a series of policy and procedural recommendations including reducing social worker ratios, streamlining the home study process and providing ongoing resources/mentorship for foster families. The agency implemented several of her suggestions which showed early promise in boosting placement retention rates.

The film and media production students also complete compelling capstone projects. For example, one group of students worked with a nonprofit organization that provides arts education to underserved youth. For their capstone, the students produced a short documentary film highlighting the meaningful impact of the nonprofit’s programs as seen through the experiences of the children, their families and volunteer instructors. The film was used by the nonprofit in grants applications and community outreach materials to garner more support. Another student created an animated public service announcement promoting wildfire prevention safety tips. The California Department of Forestry featured the PSA on their social media channels during peak wildfire season when awareness of burning restrictions was critical.

These are just a handful examples that demonstrate how capstone projects provide real-world, applied learning experiences for students across diverse fields. By directly consulting with and addressing needs of community partners and organizations, capstones allow students to utilize their academic knowledge and skills to design solutions for issues facing the public/private sectors. This bridges the classroom to practice and provides valuable work samples that showcase competencies gained, making capstones an impactful concluding experience for undergraduate degree programs. Overall capstone courses foster self-directed learning, collaboration skills and civic engagement through practical application-focused projects.

CAN YOU PROVIDE SOME EXAMPLES OF HIGH PERFORMANCE COMPUTING PROJECTS IN THE FIELD OF COMPUTER SCIENCE

The Human Genome Project was one of the earliest and most important high-performance computing projects that had a massive impact on the field of computer science as well as biology and medicine. The goal of the project was to sequence the entire human genome and identify all the approximately 20,000-25,000 genes in human DNA. This required analyzing the 3 billion base pairs that make up human DNA. Sequence data was generated at multiple laboratories and bioinformatics centers worldwide, which produced enormous amounts of data that needed to be stored, analyzed and compared using supercomputers. It would have been impossible to accomplish this monumental task without the use of high-performance computing systems that could process petabytes of data in parallel. The Human Genome Project spanned over a decade from 1990-2003 and its success demonstrated the power of HPC in solving complex biological problems at an unprecedented scale.

The Distributed Fast Multipole Method (DFMM) is an HPC algorithm that is very widely used for the fast evaluation of potentials in large particle systems. It has applications in the fields of computational physics and engineering for simulations involving electromagnetic, gravitational or fluid interactions between particles. The key idea behind the DFMM algorithm is that it can simulate interactions between particles with good accuracy while greatly reducing the calculation time from O(N^2) to O(N) using a particle clustering and multipole expansion approach. This makes it perfect for very large particle systems that can number in the billions. Several HPC projects have focused on implementing efficient parallel versions of the DFMM algorithm and applying it to cutting edge simulations. For example, researchers at ORNL implemented a massively parallel DFMM code that has been used on their supercomputers to simulate astrophysical problems with up to a trillion particles.

Molecular dynamics simulations are another area that has greatly benefited from advances in high-performance computing. They can model atomic interactions in large biomolecular and material systems over nanosecond to microsecond timescales. This provides a way to study complex dynamic processes like protein folding at an atomistic level. Examples of landmark HPC projects involving molecular dynamics include simulating the folding of complete HIV viral capsids and studying the assembly of microtubules with hundreds of millions of atoms on supercomputers. Recent HPC projects by groups like Folding@Home also use distributed computing approaches to crowdsource massive molecular simulations and contribute to research on diseases. The high fidelity models enabled by ever increasing computation power are providing new biological insights that would otherwise not be possible through experimental means alone.

HPC has also transformed various fields within computer science itself through major simulation and modeling initiatives. Notable examples include simulating the behavior of parallel and distributed systems, development of new parallel algorithms, design and optimization of chip architectures, optimizing compilers for supercomputers and studying quantum computing architectures. For instance, major hardware vendors routinely simulate future processors containing billions of transistors before physically fabrication them to save development time and costs. Similarly, studying algorithms for exascale architectures requires first prototyping them on petascale machines through simulation. HPC is thus an enabler for exploring new computational frontiers through in silico experimentation even before the actual implementations are realized.

Some other critical high-performance computing application areas in computer science research that leverage massive computational resources include:

Big data analytics: Projects involving analyzing massive datasets from genomics, web search, social networks etc. on HPC clusters and using techniques like MapReduce. Examples include analyzing NASA’s satellite data or commercial applications by companies like Facebook, Google.

Artificial intelligence: Training very large deep neural networks on datasets containing millions or billions of images/records requires HPC resources with GPUs. Self-driving car simulations, protein structure predictions using deep learning are examples.

Cosmology simulations: Modeling the evolution of the universe and formation of galaxies using computational cosmology on some of the largest supercomputers. Insights into dark matter distribution, properties of the early universe.

Climate modeling: Running global climate models with unprecedented resolution to study changes, make predictions. Projects like CMIP, analyzing petascale climate data.

Cybersecurity: Simulating network traffic, studying botnet behavior, malware analysis, encrypted traffic analysis require high performance systems.

High-performance computing has been instrumental in solving some of the biggest challenges in computer science as well as enabling discovery across a wide breadth of scientific domains by providing massively parallel computational capabilities that were previously unimaginable. It will continue powering innovations in exascale simulations, artificial intelligence, and many emerging areas in the foreseeable future.

WHAT ARE SOME COMMON RESEARCH METHODS USED IN NURSING CAPSTONE PROJECTS

Nursing capstone projects allow nursing students to demonstrate their knowledge and skills attained throughout their nursing program. These projects involve conducting an original nursing research study on a topic of relevance to nursing practice, education, administration or theory. There are a variety of research methods that can be utilized in nursing capstone projects, with the appropriate method depending on the nature and purpose of the research study. Some of the most common research methods used include:

Quantitative Research Methods:

Descriptive research designs: These aim to objectively describe phenomena through collecting numerical data. They do not involve manipulating variables. Common descriptive designs include survey research, observational studies, case studies, and record reviews. Survey research involving questionnaires or structured interviews is very common in nursing capstone projects to collect data on topics such as patient/staff experiences, attitudes, beliefs and behaviors.

Correlational research designs: These aim to discover relationships between variables through statistical analysis without manipulating variables. They may examine how two variables such as patient characteristics and health outcomes are related. Correlation does not imply causation.

Experimental research designs: These aim to determine cause-and-effect relationships through manipulating an independent variable and measuring its effect on a dependent variable. Randomized controlled trials and non-randomized control group pre-test/post-test designs are examples. Experimental designs are less common in capstone projects due to ethical and feasibility issues related to intentionally manipulating patient care.

Statistical analysis: Quantitative data collected through descriptive, correlational or experimental designs is typically analyzed through descriptive and inferential statistical tests using software like SPSS. Common analytic strategies include frequencies, measures of central tendency, hypothesis testing through t-tests, ANOVA, chi-square, correlation, and regression.

Qualitative Research Methods:

Phenomenological research: Aims to describe the essence of a lived experience around a phenomenon for several individuals. Often involves in-depth interviews to collect detailed descriptions which are then analyzed for themes. Focuses on understanding subjective experience rather than objective measurement.

Grounded theory research: Focuses on building theory through constant comparative analysis of qualitative data as it relates to categories and their properties. The goal is to generate a conceptual framework or theory to explain processes related to the topic. Data collection may involve interviews and observations coded and analyzed for emerging categories.

Ethnographic research: Focuses on understanding cultural behaviors, beliefs and interactions of a whole group who share some common trait, typically studied through extensive fieldwork over time using observation, interviewing and immersion. Less common in capstone due to time and resource demands.

Narrative research: Aims to explore life experiences through stories told by individuals in interviews or documents. Data analysis involves restorying the narrative to investigate the meaning individuals ascribe to their experience. Stories are interpreted for the researcher’s understanding rather than presenting an objective facts.

Content analysis: A research method for analyzing textual data through objective coding and categorizing patterns or themes within the content. Can be used to systematically evaluate written, electronic or visual communication data. Both qualitative and quantitative content analysis approaches exist.

Mixed Methods Research:

Convergent parallel mixed methods design: Collects quantitative and qualitative data simultaneously, analyzes separately, then mixes by comparing and contrasting results. Allows for a more comprehensive understanding through triangulation of findings.

Explanatory sequential mixed methods design: Collects quantitative data first, analyzes, then builds on results with in-depth qualitative follow up to help explain initial results. Gives voice to numeric outcomes.

Embedded mixed methods design: Collects both types of data within a predominant quantitative or qualitative design. Quantitative data used to support qualitative themes or vice versa for completeness.

Multi-phase mixed methods design: Involves collecting multiple forms of data using different designs over an extended timeframe in distinct phases, such as pilot and intervention/outcome testing.

To summarise, nursing students have a variety of robust research approaches and analytical techniques available to conduct rigorous nursing capstone research projects exploring topics relevant to evidence-based practice. Both quantitative and qualitative methods are commonly used, often in mixed designs, depending on the best fits with the research question, objectives, resources and intended outcomes of the study. Choosing the right method is vital for high quality nursing research.
